Graphical data is overlaid on the map indicating the rainfall detected by
ground based radar for a speciﬁc area. The colors indicating increasing levels
of rainfall progresses from light green for light rainfall to red for heavy rainfall.
Review the Limitations section in the front of this guide for the limitations that
apply to the Connext data. Rainfall data is color coded as follows:

The "No Coverage" color indicates that no data is available for that area, and
rainfall in that area is unknown.
When weather data is received, the airborne system will display that data for
20 minutes. If no new data has been received for a given area, the rainfall will
be removed after 20 minutes and the area will revert back to the "No Coverage"
color.
The Connext Weather Function is based on a ground-to-air data link and
requires that the appropriate ground systems are broadcasting weather data and
the aircraft is within reception range of the Ground Broadcast Transceiver (GBT).

METARs are generally updated hourly, but some site are more frequent. Special
updates are done as conditions warrant. METARs typically contain information
about the temperature, dew point, wind, precipitation, cloud cover, cloud
heights, visibility, and barometric pressure. They can also contain information
on precipitation amounts, lightning, and other critical data. METARs are shown

FIS-B Weather
Foreword
The Flight Information Services (FIS-B) function is capable of displaying text
and graphic weather information with GDL 88 installations. No subscription for
FIS-B services is required with the GDL 88.
The FIS-B Function is a graphic weather display capable of displaying
graphical weather information on UAT equipped installations. Graphical data is
overlaid on the map indicating the rainfall detected by ground based radar for a
speciﬁc area. Colors are used to identify the different NEXRAD echo intensities
(reﬂectivity) measured in dBZ (decibels of Z). “Reﬂectivity” (designated by the
letter Z) is the amount of transmitted power returned to the radar receiver.
The dBZ values increase as returned signal strength increases. Precipitation
intensity is displayed using colors corresponding to the dBZ values. Review the
Limitations section in the front of this guide for the limitations that apply to the
FIS-B data. An example of how rainfall data is color coded follows:

FIS-B NEXRAD
Foreword
WSR-88D weather surveillance radar or NEXRAD (NEXt generation RADar) is
a Doppler radar system that has greatly improved the detection of meteorological
events such as thunderstorms, tornadoes, and hurricanes. An extensive network
of NEXRAD stations provides almost complete radar coverage of the continental
United States, Alaska, and Hawaii. The unobstructed range of each NEXRAD is
124 nautical miles.

There are possible abnormalities regarding displayed NEXRAD images. Some,
but not all, causes of abnormal displayed information include:
• Ground Clutter
Direct-To
Proc
• Strobes and spurious radar data
Charts
• Sun strobes, when the radar antenna points directly at the sun
• Military aircraft deploy metallic dust which can cause alterations in radar
scans
• Interference from buildings or mountains, which may cause shadows
• Scheduled maintenance may put a radar off-line

NEXRAD Limitations
Terrain
Certain limitations exist regarding the NEXRAD radar displays. Some, but
not all, are listed for the user’s awareness:
• The Regional NEXRAD “pixels” are 1.5 minutes (1.5 nautical miles
= 2.78 km) wide by 1 minute (1 nautical miles = 1.852 km) tall. The
CONUS NEXRAD “pixels” are 7.5 minutes (7.5 nautical miles = 13.89
km) wide by 5 minutes (5 nautical miles = 9.26 km) wide. Above 60
degrees of latitude the Regional NEXRAD "pixels" are 3 minutes/nautical
miles. CONUS NEXRAD is not available above 60 degrees of latitude.
The intensity level reﬂected by the pixel will be the highest level sampled
within the area covered by each pixel.

12.6.2.3
NEXRAD Intensity
Colors are used to identify the different NEXRAD echo intensities (reﬂectivity)
measured in dBZ (decibels of Z). “Reﬂectivity” is the amount of transmitted power
returned to the radar receiver. Reﬂectivity (designated by the letter Z) covers a
wide range of signals (from very weak to very strong). So, a more convenient
number for calculations and comparison, a decibel (or logarithmic) scale (dBZ),
is used. The dBZ values increase as the strength of the signal returned to the
radar increases.
12.6.2.4 NEXRAD
When enabled, NEXRAD weather information is shown. Composite data
from all of the NEXRAD radar sites in the United States is shown. This data is
composed of the maximum reﬂectivity from the individual radar sweeps. The
display of the information is color-coded to indicate the weather level severity.
Refer to the legend for a description of the color code.
The NEXRAD option has selections of Regional, CONUS, or Combined
NEXRAD. CONUS NEXRAD includes a composite of available NEXRAD radar
imagery across the 48 states. Regional NEXRAD is a composite of available
NEXRAD radar imagery in a local area, showing a more detailed image
than CONUS NEXRAD. FIS-B weather data reception requires line-of-site
communication between the receiver and the ADS-B ground station. Incomplete
Regional and/or CONUS NEXRAD imagery displayed on the MAP and FIS-B
Weather Pages of the affected products is an indicator of poor FIS-B reception.
Affected Areas
Any area in the continental United States (CONUS) or Alaska where the
distance from ADS-B ground stations, or the combined effect of distance and
low altitude, is sufﬁciently great may cause poor reception. A good source of
information for ground station coverage can be found at:
http://www.faa.gov/nextgen/ﬂashmap/
Reception will improve in some affected areas as the FAA completes the
NextGen ADS-B ground station infrastructure. However, due to line-of-sight
broadcast characteristics, operators with properly installed and functioning
equipment may still receive incomplete FIS-B data when signal reception is
limited by the distance from ground stations combined with a low altitude.

FIS-B PIREPs
Pilot Weather Reports (PIREPs) provide timely weather information. When
signiﬁcant weather conditions are reported or forecast, Air Trafﬁc Control (ATC)
facilities are required to solicit PIREPs. A PIREP may contain non-forecast
adverse weather conditions, such as low in-ﬂight visibility, icing conditions,
wind shear, and turbulence. PIREPs are issued as either Routine (UA) or Urgent
(UUA). The update rate is approximately every 20 minutes.

The optional SiriusXM Satellite Radio entertainment feature of the GDL 69A
Data Link Receiver is available for the pilot’s and passengers’ enjoyment. The
GDL 69A can receive SiriusXM Satellite Radio entertainment services at any
altitude throughout the Continental U.S. Entertainment audio is not available
on the GDL 69 Data Link Receiver.
SiriusXM Satellite Radio offers a variety of radio programming over long distances
without having to constantly search for new stations. Based on signals from satellites,
coverage far exceeds land-based transmissions. SiriusXM Satellite Radio services
are subscription-based. For more information on speciﬁc service packages, visit
http://www.garmin.com/xm/.
Audio entertainment is available through the SiriusXM Satellite Radio Service
when activated in the optional installation of the GDL 69A. The GTN unit serves
as the display and control head for your remotely mounted GDL 69A. When
enabled, the SiriusXM Satellite Radio audio entertainment is accessible in the
Music function.
The information on the SiriusXM Satellite Radio display is composed of
four areas: the Active Channel, Available Channels, Category of the highlighted
channel, and the Volume setting. The Active Channel window shows the
Channel Name and Number, Artist, Song Title, and Category.

Activating SiriusXM Satellite Radio Services
The service is activated by providing SiriusXM Satellite Radio with either
one or two coded IDs, depending on the equipment. Either the Audio Radio ID
or the Data Radio ID, or both, must be provided to SiriusXM Satellite Radio to
activate the entertainment subscription. The SiriusXM Satellite Radio Activation
Instructions are included with the GDL 69A (also available at www.garmin.
com, P/N 190-00355-04).
It is not required to activate both the entertainment and weather service
subscriptions with the GDL 69A. Either or both services can be activated.
SiriusXM Satellite Radio uses one or both of the coded IDs to send an activation
signal that, when received by the GDL 69A, allows it to play entertainment
programming.
These IDs are located:

UTILITIES
Foreword
The Utilities page provides a group of features that will support your ﬂight
planning to make them easier and more efﬁcient. The Vertical Calculator
(VCALC) calculates the time to begin descent and vertical speed required
to reach a desired altitude at the chosen location. The Flight Timers feature
provides a number of timer types to assist in monitoring your time in ﬂight.
RAIM Prediction predicts if GPS coverage is available for your current location
or at a speciﬁed waypoint at any time and date. RAIM performs checks to ensure
that the GTN unit has adequate satellite geometry during your ﬂight. The Trip
Planning feature allows the pilot to view desired track (DTK), distance (DIS),
estimated time en route (ETE), en route safe altitude (ESA) and estimated
time of arrival (ETA) information for a direct-to, point-to-point between two
speciﬁed waypoints or for any programmed ﬂight plan. The Fuel Planning
feature will display fuel conditions along the active direct-to or ﬂight plan when
equipped with fuel ﬂow (FF) and/or fuel on board (FOB) sensors. The DALT/
TAS/Winds feature performs calculations about Altitude, Airspeed, and Winds.
The Scheduled Messages function allows you to create scheduled messages by
Message, Type, and setting a Timer. The Checklists function provides a built-in
method of reviewing your aircraft checklist. The Clean Screen function will lock
the touchscreen so the display can be cleaned without activating any functions.

RAIM Prediction
Foreword
RAIM Prediction predicts if GPS coverage is available for your current location
or at a speciﬁed waypoint at any time and date. RAIM performs checks to
ensure that the GTN unit has adequate satellite geometry during your ﬂight.
RAIM availability is near 100% in Oceanic, En Route and Terminal phases
of ﬂight. Because the FAA’s TSO requirements for non-precision approaches
specify signiﬁcantly better satellite coverage than other ﬂight phases,
RAIM may not be available when ﬂying some approaches. The GTN unit
automatically monitors RAIM during approach operations and warns you if
RAIM is not available. In such cases, use a non-GPS based approach. RAIM
prediction helps you plan for a pending ﬂight to conﬁrm GPS operation during
an approach.
RAIM prediction only predicts the availability of Fault Detection (FD)
integrity in the absence of SBAS corrections. It cannot predict the availability
of LPV or L/VNAV approaches. The FAA provides a NOTAM service for LPV
approach availability.

key.

Trip Planning
The GTN 7XX allows the pilot to view desired track (DTK), distance (DIS),
estimated time en route (ETE), en route safe altitude (ESA) and estimated time of
arrival (ETA) information for a direct-to, point-to-point between two speciﬁed
waypoints or for any programmed ﬂight plan. This item also displays the
sunrise/sunset times for your destination waypoint (for the selected departure
date). All times are based on the time set in System-Setup. For trip planning
inputs: departure time and date are manually entered, while ground speed can
be provided by sensor data, if selected.
The trip statistics are calculated based on the selected starting and ending
waypoints and the trip planning inputs.
In Flight Plan mode with a stored ﬂight plan selected, and the entire ﬂight
plan (CUM) selected, the waypoints are the starting and ending waypoints of the
selected ﬂight plan.
In Flight Plan mode with a stored ﬂight plan selected, and a speciﬁc leg
selected, the waypoints are the endpoints of the selected leg.

7/9/2015 2:08:33 PM
In Point-To-Point mode these are manually selected waypoints (if there is an
active ﬂight plan, these default to the endpoints of the active leg).
Some of the calculated trip statistics are dashed when the selected leg of the
active ﬂight plan has already been ﬂown.
• Desired Track (DTK) - DTK is shown as nnn° and is the desired track
between the selected waypoints. It is dashed unless only a single leg is
selected.
• Distance (DIS) - The distance is shown in tenths of units up to 99.9, and
in whole units up to 9999.
• Estimated time en route (ETE) - ETE is shown as hours:minutes until less
than an hour, then it is shown as minutes:seconds.
• Estimated time of arrival (ETA) - ETA is shown as hours:minutes and is
the local time at the destination.
- If in Point-To-Point mode then the ETA is the ETE added to the
departure time.
- If a ﬂight plan other than the active ﬂight plan is selected it shows the
ETA by adding to the departure time all of the ETEs of the legs up
to and including the selected leg. If the entire ﬂight plan is selected,
then the ETA is calculated as if the last leg of the ﬂight plan was
selected.
- If the active ﬂight plan is selected the ETA reﬂects the current position
of the aircraft and the current leg being ﬂown. The ETA is calculated
by adding to the current time the ETEs of the current leg up to and
including the selected leg. If the entire ﬂight plan is selected, then the
ETA is calculated as if the last leg of the ﬂight plan was selected.
• En Route safe altitude (ESA) - The ESA is shown as nnnnnFT.
• Destination sunrise and sunset times - These times are shown as
hours:minutes and are the local time at the destination.
NOTE: The capability of using Sensor Data for the trip planning functions
is available in SW Versions 2.00, 4.10, and later.

Fuel Planning
Fuel Planning — This item displays fuel conditions along the active
direct-to or ﬂight plan. You may manually enter fuel ﬂow, ground speed
(GS) and fuel on board ﬁgures for planning purposes. Fuel planning ﬁgures
can be displayed not only for the currently active ﬂight plan or direct-to,
but also point-to-point between two speciﬁed waypoints and for any programmed ﬂight plan.
Fuel on board and fuel ﬂow may be manually entered in the unit start-up
sequence and used to recalculate fuel on board as it is consumed. When fuel
ﬂow or fuel on board is manually entered, the ﬁgures are retained the next time
you view the page (with fuel on board continuously recalculated).

DALT/TAS/Winds
Density Alt / TAS / Winds — indicates the theoretical altitude at which
your aircraft performs depending upon several variables, including indicated
altitude (Indicated ALT), barometric pressure (BARO) and total air temperature (TAT; the temperature, including the heating effect of speed, read on
a standard outside temperature gauge). This item computes true airspeed
(TAS) and density altitude, based upon the factors above. Also, this feature
determines winds aloft — the wind direction and speed — and a head
wind/tail wind component, based on true airspeed, aircraft heading (HDG)
and ground speed. When a FADC provides pressure altitude and the Use
Sensor Data option is selected, the Baro key will not be present in the edit
mode and the Baro indication will not be shown in computed results.

Serial Number and System ID
The following databases are stored on Supplemental Data Cards provided by
Garmin:
• Terrain – The terrain database contains terrain mapping data. It is updated
periodically and has no expiration date. Approximately one minute is
required to verify the rotorcraft terrain database on start up.
• Obstacles – The obstacles database contains data for obstacles, such as
towers, that pose a potential hazard to aircraft. Obstacles 200 feet and
higher are included in the obstacle database. The rotorcraft database
includes all reported obstacles regardless of height. It is very important to
note that not all obstacles are necessarily charted and therefore may not
be contained in the obstacle database. This database is updated on a 56day cycle. Obstacles will still be shown after the database has expired.

Several obstacle database options are available. Obstacle databases created
for GTN software version 5.10 or later include all power lines or only HOT
lines depending on the type of obstacle database installed. Hazardous
Obstacle Transmission (HOT) Lines are those power lines that are co-located
with other FAA-identiﬁed obstacles. The installed obstacle database type
can be veriﬁed on the System Status page. Power line data is available for
the contiguous United States as well as small parts of Canada and Mexico.
• SafeTaxi – The SafeTaxi database contains detailed airport diagrams
for selected airports. These diagrams aid in following ground control
instructions by accurately displaying the aircraft position on the map in
relation to taxiways, ramps, runways, terminals, and services. This database
is updated on a 56-day cycle. SafeTaxi will still be shown after it has expired.
• FliteCharts – The FliteCharts database contains procedure charts for the
United States only. This database is updated on a 28-day cycle. If not updated
within 180 days of the expiration date, FliteCharts no longer functions.
• Basemap - The Basemap database contains land and water data, such as
roads, boundaries, rivers, and lakes.
• Aviation – The Navigation database is updated on a 28 day cycle. Navigation
database updates are provided by Garmin and may be downloaded from the
Garmin web site “http://ﬂy.garmin.com” or from Jeppesen at "http://www.
jeppdirect.com/Garmin" onto a Garmin provided Supplemental Datacard.
Contact Garmin at http://ﬂy.garmin.com for navigation database updates
and update kits.
• Charts – The optional ChartView database is updated on a 14 day cycle. The
ChartView database is provided directly from Jeppesen. Contact Jeppesen
(www.jeppesen.com) for ChartView subscription and update information.
NOTE: Do not use SafeTaxi or Chartview functions as the basis for ground
maneuvering. SafeTaxi and Chartview functions do not comply with the
requirements of AC 20-159 and are not qualiﬁed to be used as an airport
moving map display (AMMD). SafeTaxi and Chartview are to be used by
the ﬂight crew to orient themselves on the airport surface to improve pilot
situational awareness during ground operations.

16.1.3.1 Database Info
The Database Info page shows the Current databases, databases on Standby
on the SD card for future use, and database conﬂicts. Current databases show all
databases that are currently being used. Standby databases are loaded onto the
card, but are not being used. Database conﬂicts are shown and can be resolved
in the Conﬂicts tab.
16.1.3.2 Database Sync Operation
Database SYNC allows the GTN to synchronize databases from a single unit.
The pilot only needs to update a single database card and the new databases are
automatically SYNC'd through the units connected in the cockpit and conﬁgured
for Database Syncing.

• Chartview (when support is added by Jeppesen)
Trafﬁc
• FliteCharts
• Basemap
Terrain
When Database SYNC is enabled in the LRUs and a database card is inserted
that is created for Database SYNC, the GTN will coordinate with the other
LRUs in the cockpit to determine which unit has the newest databases. Once
the determination has occurred, the connected LRUs will begin to transfer the
databases. This process may take several minutes. The status of the database
transfers to a unit can be viewed on the System Status page under the “Standby”
tab. The GTN will display the source of the received databases (in this example:
“Database SYNC - GTN #2”). If a database transfer is pending, completed, or not
authorized, the status will also be indicated.
When the transfer is complete, if there are new and current databases to
be used, and if the aircraft is stopped and has yet to takeoff, the pilot will
be prompted with the option to restart the unit that has the new databases
transferred to it. During the restart process, the unit will prompt you to update
(transfer from the card to the unit's memory) to the newer databases so they can
be used.

The GTN will use Database SYNC in the background to SYNC the standby
database with other LRUs in the cockpit. As a result, when the standby database
becomes effective, the pilot will be prompted on all LRUs to update to the new
database.
If a the standby database is out of date or not yet effective, the pilot will not
be prompted to update to that database until it becomes effective. This prevents
the pilot from accidentally overwriting the effective, active database.
If the pilot does actually want to overwrite the active database with a not yet
effective or out of date database, they can do so by pressing and holding the
small right knob while applying power to the GTN.

The GPS receiver is in 3D navigation mode and
computes altitude using satellite data.
The GPS receiver is in 3D navigation mode and

The GPS Status Page also indicates the accuracy of the position ﬁx, using
Horizontal Figure of Merit (HFOM), Vertical Figure of Merit (VFOM), and
Estimated Position Uncertainty (EPU). HFOM and VFOM represent the 95%
conﬁdence levels in horizontal and vertical accuracy. The lowest numbers are
the best accuracy and the highest numbers are worse. EPU is the horizontal
position error estimated by the Fault Detection and Exclusion (FDE) algorithm,

page. Regardless of the EPU value displayed, the LOI annunciation is the
controlling indication for determining the integrity of the GPS navigation
solution.
NOTE: The FDE Prediction program is used to predict FDE availability.
This program must be used prior to all oceanic or remote area ﬂights for
all operators using the GTN as a primary means of navigation under FAR
parts 91, 121, 125, and 135. The FDE program is part of the GTN trainer,
available for download from the GTN product information page on Garmin’s
web site, www.garmin.com.
If the GTN has not been operated for a period of six months or more,
acquiring satellite data to establish almanac and satellite orbit information can
take 5 to 10 minutes.
The Time and other data may not be displayed until the unit has acquired
enough satellites for a ﬁx.

Circle of Uncertainty
The Circle of Uncertainty depicts an area where the ownship location is
guaranteed to be when the aircraft location cannot be accurately determined.
The area of the Circle of Uncertainty becomes larger as GPS horizontal accuracy
degrades and smaller as it improves. The Circle of Uncertainty is shown only
when the aircraft is on the ground. The Circle of Uncertainty area is transparent
so that features within it may still be seen.

Crossﬁll
Dual units may be interfaced to crossﬁll information between the two units.
This option will not be available unless dual units are conﬁgured.
When Crossﬁll is turned on with one GTN, it is automatically turned on in the
other GTN. Some items are always crossﬁlled regardless of the crossﬁll setting;
others are dependent on the crossﬁll setting.
The GTN can be can also be interfaced with the GNS 400W/500W units. The
GTN can automatically send the Active Flight Plan and active Direct-To course to
the GNS unit. The GTN User Waypoints can be manually sent to the GNS unit. The
GNS unit can manually send its User Waypoints to the GTN unit.
Waypoint names longer than six characters, or duplicates, sent from the GTN
unit to the GNS unit will replace some characters with a "+" sign, while leaving
signiﬁcant characters to aid in identiﬁcation (such as, USR003 becomes US+003).
NOTE: Upon crossﬁll being activated, the GTNs may take up to 10 seconds
to crossﬁll the ﬂight plans. The pilot must verify the ﬂight plan in each unit
prior to use. The GTN and GNS units must have databases with the same cycle.
Charts
Wpt Info
NOTE: When GPS navigation is lost in either unit, crossﬁlling may not be
available until GPS is restored in both units. Crossﬁlling will resume once the
ﬂightplan is changed on one of the units or crossﬁll is re-enabled.
Map

NOTE: If two GTN 7XX units are crossﬁlled, then the same type (ChartView

CDI Scale Selection
The CDI source and ILS CDI Capture type may be selected manually or
automatically. The selected CDI Scale will be reﬂected in the annunciation bar at
the bottom of the display.
CDI Scale Selection allows you to deﬁne the scale for the course deviation
indicator (both on the GTN unit's on-screen CDI and the external CDI). The
scale values represent full scale deﬂection for the CDI to either side. The default
setting is “Auto”. At this setting, the CDI scale is set to 2.0 NM during the
“en route” phase of ﬂight. Within 31 NM (terminal area) of your destination
airport, the CDI scale linearly ramps down to 1.0 NM over a distance of 1 NM.
Likewise, when leaving your departure airport the CDI scale is set to 1.0 NM
and gradually ramps up to 2 NM beyond 30 NM (from the departure airport).
During GPS approach operations the CDI scale gradually transitions down to an
angular CDI scale. At 2.0 NM before the ﬁnal approach ﬁx (FAF), CDI scaling is
tightened from 1.0 NM to the angular full scale deﬂection (typically the angular
full-scale deﬂection is 2.0°, but will be as deﬁned for the approach).
If a lower CDI scale setting is selected (i.e., 1.0 or 0.3 NM), the higher scale
settings are not selected during ANY phase of ﬂight. For example, if 1.0 NM is
selected, the GTN unit uses this for en route and terminal phases and ramps down
further during an approach. Note that the Horizontal Alarm (HAL) protection

limits listed below follow the selected CDI scale, unless corresponding ﬂight
phases call for lower HAL. For example, if the 1.0 NM CDI setting is selected,
full-scale deﬂection during approach will still follow the approach CDI scale
settings.

Backlight Settings
Foreword
The backlighting of the display and bezel keys can be adjusted automatically
or manually. The default setting (automatic backlighting adjustment) uses
photocell technology to automatically adjust for ambient lighting conditions.
Photocell calibration curves are pre-conﬁgured to optimize display appearance
through a broad range of cockpit lighting conditions. A manual offset creates
a deviation form the normal curve. Manual adjustments may be made from
+100% to -10%. The negative adjustment is limited to prevent the backlight
from being accidently decreasing the backlight to the point where the display of
information could not be seen.
The backlight offset function is not available when a dimmer input is active.
The GTN is capable of accepting lighting inputs from the built-in photocell,
aircraft dimmer bus, or both. If the lighting is not satisfactory, contact the
installer to adjust the curves.
Manual backlighting adjustment can be accomplished using the existing
instrument panel dimmer bus or the following procedures.

16.11.1 Operation
Foreword
Data output from the GTN and Flight Stream 210 occurs automatically
and requires no pilot action (such as, ﬂight plan, GPS position, and attitude).
Additionally, ADS-B trafﬁc and weather can be output from the Flight Stream
when connected to a GDL 88 and XM WX and SiriusXM satellite radio
information can output when connected a GDL 69.
From the Connext Setup page, the pilot can enable/disable ﬂight plan
importing, change the Flight Stream Bluetooth name, and manage paired
devices.
The device status indicates if the portable device is connected and
communicating with the Flight Stream. The “Auto-Reconnect” setting determines
if the Flight Stream will automatically connect to up to four devices when in
range. When this setting is disabled, the pilot must initiate the connection from
the device. Removing a device from this page by pressing “Remove” will require
the device to be paired again before transferring data.
NOTE: If the pairing is removed from either device (portable device or
GTN) it must be removed on the other device before a new pairing to that
same device is established again. Essentially, pairing must be removed on
both devices before repairing.

From the Connext Setup page, the pilot can enable/disable Bluetooth, change
the GMA 35c Bluetooth name, and manage paired devices. On the Paired
Devices page, the device status indicates if the portable device is connected and
communicating with the GMA 35c. Only one portable device can be connected
to the GMA 35c at a time. To connect a different device when one is already
connected, the existing connection must be ended by removing the portable
device pairing from the GMA 35c or by disconnecting or disabling Bluetooth on
the portable device. Removing a device from this page by pressing “Remove” will
require the device to be paired again before streaming audio.
NOTE: If the pairing is removed from either device (portable device or
GMA) it must be removed on the other device before a new pairing to that
same device is established again. Essentially, pairing must be removed on
both devices before repairing.
New devices can only be paired with the GMA 35c when it is in “Pairing

There are several reference datums that waypoints can be surveyed against.
TSO-C146 normally requires that all waypoints be referenced to the WGS84
datum, but allows for navigation to waypoints that are not referenced to the
WGS84 datum so long as the pilot is notiﬁed. Certain waypoints in the navigation
database are not referenced to the WGS84 datum, or their reference datum is
unknown. If this is the case, this message is displayed. Garmin cannot determine
exactly how close the non-WGS84 referenced waypoint will be to the WGS84
datum that the GTN uses. Typically, the distance is within two nautical miles.
The majority of non-WGS84 waypoints are located outside of the United States.

The navigation database is updated on a 28-day cycle. Navigation database
updates are provided by Garmin and may be downloaded from the Garmin web
site “ﬂy.garmin.com” onto a Garmin provided Supplemental Data card. Contact
Garmin at ﬂy.garmin.com for navigation database updates and update kits. The
Navigation database is stored internally and the data card is only used to transfer
the database into the unit.
The optional ChartView database is updated on a 14 day cycle. The ChartView
database is provided directly from Jeppesen. Contact Jeppesen (www.jeppesen.
com) for ChartView subscription and update information. An enablement card
that is purchased from Garmin is separate from the Jeppesen database and is
required to enable ChartView.
NOTE: Garmin requests that the flight crew report any observed
discrepancies related to database information. These discrepancies could
come in the form of an incorrect procedure, incorrectly identiﬁed terrain,
obstacles and ﬁxes, or any other displayed item used for navigation or
communication in the air or on the ground. Go to “FlyGarmin.com” and at
the bottom of the page select “Aviation Data Error Report.”

Garmin Databases
Foreword
NOTE: The data contained in the terrain and obstacle databases comes from
government agencies. Garmin accurately processes and cross-validates the
data, but cannot guarantee the accuracy and completeness of the data.
The Supplemental Data Card should not be removed except to update the

The Garmin databases can be updated by following the instructions on ﬂy.
garmin.com. Once the updated ﬁles have been downloaded from the web site, a
PC equipped with an appropriate SD card reader is used to unpack and program
the new databases onto the existing Supplemental Data Cards. The following
equipment is required to perform the update:
• Windows-compatible PC computer (Windows 2000, XP, Vista, or Windows

Common Problems/Troubleshooting Tips for Databases
Getting
Started
• SD Cards
- The supplied SD cards, and most commercially available SD cards, have
a small sliding tab located on the top left of the card (when viewing the
card label-side up).
Audio &
Xpdr Ctrl
Com/Nav
- When the sliding tab is in the Down position (as in farther away from
the gold contacts on the back of the card), you will not be able to write
data to the card, as it will be write protected.
FPL
Direct-To
- The tab must be in the Up position to work correctly.
Proc
• Card Programmer
- If a card programmer is having trouble ﬁnding or writing data to
the SD cards, you may have to upgrade to a High Capacity SD card
programmer.
Charts
Wpt Info
- SD cards with a capacity of 4GB are considered high capacity.
Map
- Most non-high capacity card programmers will not work with a high
capacity SD card. High capacity card programmers can be easily
purchased at a consumer electronics store.
Trafﬁc
- Ensure that your card programmer is not plugged into a USB hub, your
computer screen, or your keyboard.
Terrain
Weather
Nearest
- Make sure it is plugged directly into your computer (the back of the
computer, if using a desktop computer).
Services/
Music
• If you accidentally place a ﬁle onto the wrong card, call Garmin’s Aviation
Product Support team to look at the ﬁles and delete the proper ﬁles.
- Do not format the cards

Updating Garmin Databases
Foreword
1. Download the data to the data cards from the appropriate web site.
Getting
Started
2. Insert Navigation Database SD card in the slot of the GTN 7XX.
3. Apply power to the GTN 7XX System. View the power-up splash screen. Check
that the databases are initialized and displayed on the splash screen. Some
databases can take up to 15 minutes to update.
4. The database update page will prompt to either Update or Continue. Touch the
Update key to update the database(s). Touch the Continue key to continue
to normal operation without updating a database. This process will repeat for
each database that is available on the card for updating.
5. After the database(s) have completed the update process, touch OK to continue
the normal progression of start-up displays.
6. From the Home page, touch the System key. Then, touch the System Status
key.
7. Check that all databases are current and there are no errors. If a database is
highlighted in yellow, it is either expired or the GTN 7XX can not determine the
date.

Glove Qualiﬁcation Procedure
Foreword
This procedure is used to qualify a speciﬁc glove for use with the GTN system
by guiding the user through a variety of tasks that use the touchscreen. Due to
differences in ﬁnger size, glove size, and touchscreens between the 6XX or 7XX
unit, the qualiﬁcation granted by this procedure is speciﬁc to the pilot/glove and
6XX or 7XX combination. GTN 7XX and 6XX units must be evaluated separately.
The GTN touchscreen uses capacitive touch technology to sense the proximity
of skin to the display. A glove increases the distance between skin and the display
glass and may reduce the ability of the GTN to detect touches. Therefore, when
selecting a glove for use with the GTN, thinner gloves tend to work better than
thicker gloves. Leather gloves and gloves designed to work speciﬁcally with
capacitive touchscreen devices are often found to be acceptable. Additionally,
altering your touch technique to use the pad of your ﬁnger to touch the unit
rather than the tip will increase the touchscreen sensitivity while using gloves.
This qualiﬁcation must be completed on the ground. Performing this
procedure in ﬂight is not authorized. Table 19-1 contains tasks that are required
to qualify a glove. Table 19-2 contains tasks that are not required to qualify a
glove, but may limit the manner in which some functions are accessed while a
glove is worn.

1. Sit in the pilot’s seat.
2. Start the GTN in Demo mode by pressing and holding the Direct To key during
power up.
3. Perform the tasks listed in Table 19-1 and Table 19-2 with an non-gloved hand.
You do not need to record any results for this step.
4. Perform the tasks listed in Table 19-1 and Table 19-2 with a gloved hand. For
each task, determine whether the operation is the same or worse as it was
without the glove. Record the results in Table 19-1 and Table 19-2. Items that
may cause the operation to be worse include, but are not limited to:
a. Multiple attempts to select a key
b. Unintentional selection of adjacent keys
c. Excessive force on the touchscreen to select a key
5. If all applicable tasks in Table 19-1 respond in the same way with and without
a glove then the glove used to complete these tasks may be used by the pilot
