Introduction 1

Inserting Memory Cards

You can use optional memory cards in the chartplotter. Map

cards allow you to view high-resolution satellite imagery and

aerial reference photos of ports, harbors, marinas, and other

points of interest. You can use blank memory cards to

transfer data such as waypoints, routes, and tracks to

another compatible Garmin chartplotter or a computer.

1Open the access door À on the front of the chartplotter.

2Insert the memory card Á with the label facing to the

right.

3Press the card in until it clicks.

4Close the door.

Charts and 3D Chart Views

The chartplotters have a basic imagery map. The charts and

3D chart views listed below are available on the chartplotter.

The charts and views that are available depend on the map

data and accessories used.

You can access the charts and chart views by selecting

Charts.

Navigation Chart: Shows navigation data available on your

pre-loaded maps and from supplemental maps, if

available. The data includes buoys, lights, cables, depth

soundings, marinas, and tide stations in an overhead

view.

Perspective 3D: Provides a view from above and behind the

boat (according to your course) and provides a visual

navigation aid. This view is helpful when navigating tricky

shoals, reefs, bridges, or channels, and is beneficial when

trying to identify entry and exit routes in unfamiliar

harbors or anchorages.

Mariner’s Eye 3D: Shows a detailed, three-dimensional view

from above and behind the boat (according to your

course) and provides a visual navigation aid. This view is

helpful when navigating tricky shoals, reefs, bridges, or

channels, and when trying to identify entry and exit routes

in unfamiliar harbors or anchorages.

NOTE: Mariner's Eye 3D and Fish Eye 3D chart views

are available with premium charts, in some areas.

Fish Eye 3D: Provides an underwater view that visually

represents the sea floor according to the chart

information. When a sonar transducer is connected,

suspended targets (such as fish) are indicated by red,

green, and yellow spheres. Red indicates the largest

targets and green indicates the smallest.

NOTE: Mariner's Eye 3D and Fish Eye 3D chart views

are available with premium charts, in some areas.

Fishing Chart: Provides a detailed view of the bottom

contours and depth soundings on the chart. This chart

removes navigational data from the chart, provides

detailed bathymetric data, and enhances bottom contours

for depth recognition. This chart is best for offshore deep-

sea fishing.

NOTE: The offshore Fishing chart is available with

premium charts, in some areas.

Radar Overlay: Superimposes radar information on the

Navigation chart or the Fishing chart, when the

chartplotter is connected to a radar. This feature is not

available with all models.

Navigation Chart and Offshore Fishing

Chart

NOTE: The offshore Fishing chart is available with premium

charts, in some areas.

The Navigation and Fishing charts allows you to plan your

course, view map information, and follow a route. The Fishing

chart is for offshore fishing.

To open the Navigation chart, select Charts > Navigation

Chart.

To open the Fishing chart, select Charts > Fishing Chart.

Zooming In and Out of the Chart

The zoom level is indicated by the scale number at the

bottom of the chart. The bar under the scale number

represents that distance on the chart.

•Select to zoom out.

•Select to zoom in.

Panning the Chart

You can move the chart to view an area other than your

present location.

1From the chart, drag the navigation screen or use the

arrow keys.

2Select Stop Panning or Back to stop panning and return

the screen to your present location.

Selecting an Item on the Map Using the Device

Keys

1From a chart or 3D chart view, select , , , or to

move the cursor.

2Select Select.

Other features common to most charts include depth contour

lines (with deep water represented in white), intertidal zones,

spot soundings (as depicted on the original paper chart),

navigational aids and symbols, obstructions, and cable areas.

Navigating to a Point on the Chart

CAUTION

The Auto Guidance feature is based on electronic chart

information. That data does not ensure obstacle and bottom

clearance. Carefully compare the course to all visual

sightings, and avoid any land, shallow water, or other

obstacles that may be in your path.

When using Go To, a direct course and a corrected course

may pass over land or shallow water. Use visual sightings,

and steer to avoid land, shallow water, and other dangerous

objects.

NOTE: The offshore Fishing chart is available with premium

charts, in some areas.

NOTE: Auto Guidance is available with premium charts, in

some areas.

1From the Navigation chart or Fishing chart, select a

location.

2If necessary, select Select.

3Select Navigate To.

4Select an option:

• To navigate directly to the location, select Go To.

• To create a route to the location, including turns,

select Route To.

• To use Auto Guidance, select Guide To.

5Review the course indicated by the magenta line.

NOTE: When using Auto Guidance, a gray segment

within any part of the magenta line indicates that Auto

Guidance cannot calculate part of the Auto Guidance line.

This is due to the settings for minimum safe water depth

and minimum safe obstacle height.

6Follow the magenta line, steering to avoid land, shallow

water, and other obstacles.

Viewing Location and Object Information on a

Chart

You can view information about a location or an object on the

Navigation chart or the Fishing chart.

NOTE: The offshore Fishing chart is available with premium

charts, in some areas.

1From the Navigation chart or Fishing chart, select a

location or object.

A list of options appears along the right side of the chart.

The options that appear vary based on the location or

object you selected.

2Select an option:

• To view details of objects in the vicinity of the cursor,

select Review.

NOTE: Review does not appear if the cursor is not

near an object. If the cursor is near only one object,

the name of the object appears.

• To navigate to the selected location, select Navigate

To.

• To mark a waypoint at the cursor location, select

Create Waypoint.

• To view the distance and bearing of the object from

your current location, select Measure Distance.

The distance and bearing appear on the screen.

Select Set Reference to measure from a location

other than your current location.

• To view tide, current, celestial, chart notes, or local

services information near the cursor, select

Information.

Viewing Details about Navaids

From the Navigation chart, Fishing chart, Perspective 3D

chart view, or Mariner’s Eye 3D chart view, you can view

details about various types of navigation aids, including

beacons, lights, and obstructions.

NOTE: The offshore Fishing chart is available with premium

charts, in some areas.

NOTE: Mariner's Eye 3D and Fish Eye 3D chart views are

available with premium charts, in some areas.

1From a chart or 3D chart view, select a navaid.

2If necessary, select Review.

3Select the name of the navaid.

Premium Charts

CAUTION

The Auto Guidance feature is based on electronic chart

information. That data does not ensure obstacle and bottom

clearance. Carefully compare the course to all visual

sightings, and avoid any land, shallow water, or other

obstacles that may be in your path.

Optional premium charts, such as BlueChart® g2 Vision®,

allow you to get the most out of your chartplotter. In addition

to detailed marine charting, premium charts may contain

these features, which are available in some areas.

Mariner’s Eye 3D: Provides a view from above and behind

the boat for a three-dimensional navigation aid.

Fish Eye 3D: Provides an underwater, three-dimensional

view that visually represents the sea floor according to

the information on the chart.

Fishing Charts: Shows the chart with enhanced bottom

contours and without navigational data. This chart works

well for offshore deep-sea fishing.

High Resolution Satellite Imagery: Provides high-resolution

satellite images for a realistic view of the land and water

on the Navigation chart (page 4).

Aerial Photos: Shows marinas and other navigationally

significant aerial photos to help you visualize your

surroundings (page 4).

Automatic Identification System

The Automatic Identification System (AIS) enables you to

identify and track other vessels, and alerts you to area traffic.

When connected to an external AIS device, the chartplotter

can show some AIS information about other vessels that are

within range, that are equipped with a transponder, and that

are actively transmitting AIS information. The information

reported for each vessel includes the Maritime Mobile

Service Identity (MMSI), location, GPS speed, GPS heading,

time that has elapsed since the last position of the vessel

was reported, nearest approach, and time to the nearest

approach.

4 Charts and 3D Chart Views

AIS Targeting Symbols

Symbol Description

AIS vessel. The vessel is reporting AIS information. The

direction in which the triangle is pointing indicates the

direction in which the AIS vessel is moving.

Target is selected.

Target is activated. The target appears larger on the

chart. A green line attached to the target indicates the

heading of the target. The MMSI, speed, and direction of

the vessel appear beneath the target, if the details setting

has been set to Show. If the AIS transmission from the

vessel is lost, a message banner appears.

Target is lost. A green X indicates that the AIS

transmission from the vessel is lost, and the chartplotter

displays a message banner asking whether the vessel

should continue to be tracked. If you discontinue vessel

tracking, the lost target symbol disappears from the chart

or the 3D chart view.

Dangerous target in range. The target flashes while an

alarm sounds and a message banner appears. After the

alarm has been acknowledged, a solid red triangle with a

red line attached to it indicates the location and the

heading of the target. If the safe-zone collision alarm has

been set to Off, the target flashes, but the audible alarm

does not sound and the alarm banner does not appear. If

the AIS transmission from the vessel is lost, a message

banner appears.

Dangerous target is lost. A red X indicates that the AIS

transmission from the vessel is lost, and the chartplotter

displays a message banner asking whether the vessel

should continue to be tracked. If you discontinue vessel

tracking, the lost dangerous target symbol disappears

from the chart or the 3D chart view.

The location of this symbol indicates the closest point of

approach to a dangerous target, and the numbers near

the symbol indicate the time to the closest point of

approach to that target.

Heading and Projected Course of Activated AIS

Targets

When heading and course over ground information are

provided by an activated AIS target, the heading of the target

appears on a chart as a solid line attached to the AIS target

symbol. A heading line does not appear on a 3D chart view.

The projected course of an activated AIS target appears as a

dashed line on a chart or a 3D chart view. The length of the

projected course line is based on the value of the projected

heading setting. If an activated AIS target is not transmitting

speed information, or if the vessel is not moving, a projected

course line does not appear. Changes in the speed, course

over ground, or rate of turn information transmitted by the

vessel can impact the calculation of the projected course line.

When course over ground, heading, and rate of turn

information are provided by an activated AIS target, the

projected course of the target is calculated based on the

course over ground and the rate of turn information. The

direction in which the target is turning, which is also based on

the rate of turn information, is indicated by the direction of the

barb at the end of the heading line. The length of the barb

does not change.

When course over ground and heading information are

provided by an activated AIS target, but rate of turn

information is not provided, the projected course of the target

is calculated based on the course over ground information.

Showing AIS Vessels on a Chart or 3D Chart View

Before you can use AIS, you must connect the chartplotter to

an external AIS device and receive active transponder

signals from other vessels.

You can configure how other vessels appear on a chart or on

a 3D chart view. The display range configured for one chart

or one 3D chart view are applied only to that chart or to that

3D chart view. The details, projected heading, and trails

settings configured for one chart or one 3D chart view are

applied to all charts and to all 3D chart views.

have a compatible chartplotter connected to an AIS device.

The safe-zone collision alarm is used only with AIS. The safe

zone is used for collision avoidance, and can be customized.

1Select Settings > Alarms > AIS > AIS Alarm > On.

A message banner appears and an alarm sounds when

an AIS-activated vessel enters the safe-zone area around

your boat. The object is also labeled as dangerous on the

screen. When the alarm is off, the message banner and

audible alarm are disabled, but the object is still labeled

as dangerous on the screen.

determined to intersect the safe zone.

For example, to be notified of a pending intersection 10

minutes before it will likely occur, set Time To to 10, and

the alarm will sound 10 minutes before the vessel

intersects the safe zone.

AIS Distress Signals

Self-contained AIS distress signal devices transmit

emergency position reports when activated. The chartplotter

can receive signals from Search and Rescue Transmitters

(SART), Emergency Position Indicating Radio Beacons

(EPIRB), and other man overboard signals. Distress signal

transmissions are different than standard AIS transmissions,

so they appear differently on the chartplotter. Instead of

tracking a distress signal transmission for collision avoidance,

you track a distress signal transmission to locate and assist a

vessel or person.

Navigating to a Distress Signal Transmission

When you receive a distress signal transmission, a distress

signal alarm appears.

Select Review > Go To to begin navigation to the

transmission.

Radar

WARNING

The marine radar transmits microwave energy that has the

potential to be harmful to humans and animals. Before

beginning radar transmission, verify that the area around the

radar is clear. The radar transmits a beam approximately 12°

above and below a line extending horizontally from the center

of the radar. Avoid looking directly at the radar, because the

eyes are the most susceptible parts of the body.

NOTE: Not all models support radar.

When you connect your compatible chartplotter to an optional

Garmin marine radar, such as a GMR™ 1206 xHD or a GMR

24 HD, you can view more information about your

surroundings.

The GMR transmits a narrow beam of microwave energy as it

rotates to a 360° pattern. When the transmitted energy

contacts a target, some of that energy is reflected back to the

radar.

Radar Display Modes

NOTE: Not all modes are available with all radar devices and

all chartplotters.

Select Radar, and select a mode.

Cruising Mode: Shows a full-screen image of the gathered

radar information.

Harbor Mode: Intended for use in inland waters, this mode

works best with short-range signals (2 nm or less).

Offshore Mode: Intended for use in open waters, this mode

works best with long-range signals.

Sentry Mode: Allows you to put the radar into timed-transmit

mode, in which you can configure a radar transmit and

standby cycle to conserve power. You can also enable a

guard zone in this mode, which identifies a safe zone

around your boat. If you switch from Sentry mode to

another mode, the radar switches to full-time transmission

and disables all guard zones.

Radar Overlay Mode: Shows a full-screen image of the

gathered radar information on top of the Navigation chart.

The Radar overlay displays data based on the most-

recently used radar mode.

Transmitting Radar Signals

NOTE: As a safety feature, the radar enters standby mode

after it warms up. This gives you an opportunity to verify the

area around the radar is clear before beginning radar

transmission.

1With the chartplotter off, connect your radar as described

in the radar installation instructions.

2Turn on the chartplotter.

The radar warms up and a countdown alerts you when

the radar is ready.

3Select Radar.

4Select a radar mode.

A countdown message appears while the radar is starting

up.

5Select Menu > Transmit Radar.

Adjusting the Zoom Scale on the Radar

Screen

The radar zoom scale, also called the radar signal range,

represents the distance from your position (the center) to the

outermost ring.

From a Radar screen, select or .

Each ring represents an even division of the zoom scale.

For example, if the zoom scale is set at 3 miles, each ring

represents 1 mile from the center out.

Tips for Selecting a Radar Zoom Scale

The radar zoom scale, or radar signal range, indicates the

length of the pulsed signal transmitted and received by the

16 Radar

radar. As the range increases, the radar transmits longer

pulses in order to reach distant targets. Closer targets,

especially rain and waves, also reflect the longer pulses,

which can add noise to the Radar screen. Viewing

information about longer-range targets can also decrease the

amount of space available on the Radar screen for viewing

information about shorter-range targets.

• Determine what information you need to see on the

Radar screen.

For example, do you need information about nearby

weather conditions or targets and traffic, or are you more

concerned about distant weather conditions?

• Assess the environmental conditions where the radar is

being used.

Especially in inclement weather, longer-range radar

signals can increase the clutter on the Radar screen and

make it more difficult to view information about shorter-

range targets. In rain, shorter-range radar signals can

enable you to view information about nearby objects more

effectively, if the rain clutter setting is configured

optimally.

• Select the shortest effective range, given your reason for

using radar and the present environmental conditions.

Sentry Mode

Sentry mode allows you to put the radar into timed-transmit

mode, in which you can configure a radar transmit and

standby cycle to conserve power. You can also enable a

guard zone in this mode, which identifies a safe zone around

your boat and sounds an alarm when a radar object enters

the zone. Sentry mode works with all Garmin GMR model

radars.

Enabling Timed Transmit

Select Radar > Sentry > Menu > Sentry Setup > Timed

VRM and EBL

The variable range marker (VRM) and the electronic bearing

line (EBL) measure the distance and bearing from your boat

Radar 17

to a target object. On the Radar screen, the VRM appears as

a circle that is centered on the present location of your boat,

and the EBL appears as a line that begins at the present

location of your boat and intersects the VRM. The point of

intersection is the target of the VRM and the EBL.

Showing the VRM and the EBL

The VRM and the EBL configured for one mode are applied

to all other radar modes.

From a Radar screen, select Menu > Show VRM/EBL.

Adjusting the VRM and the EBL

Before you can adjust the VRM and the EBL, you must show

them on the Radar screen (page 18).

You can adjust the diameter of the VRM and the angle of the

EBL, which moves the intersection point of the VRM and the

EBL. The VRM and the EBL configured for one mode are

applied to all other radar modes.

2Select Measure Distance.

The range and the bearing to the target location appear in

the upper-left corner of the screen.

Radar Overlay

When you connect your chartplotter to an optional Garmin

marine radar, you can use the Radar overlay to overlay radar

information on the Navigation chart or on the Fishing chart.

The Radar overlay superimposes radar information on the

Navigation chart or the Fishing chart. Data appears on the

Radar overlay based on the most recently used radar mode

(such as Harbor, Offshore, or Sentry), and all settings

configurations applied to the Radar overlay are also applied

to the last-used radar mode. For example, if you use Harbor

mode and then you switch to the Radar overlay, the Radar

overlay would show Harbor mode radar data. If you changed

the gain setting using the Radar overlay menu, the gain

setting for Harbor mode would change automatically.

Radar Overlay and Chart Data Alignment

When using the Radar overlay, the chartplotter aligns radar

data with chart data based on the boat heading, which is

based by default on data from a magnetic heading sensor

connected using a NMEA 0183 or NMEA 2000 network. If a

heading sensor is not available, the boat heading is based on

GPS tracking data.

GPS tracking data indicates the direction in which the boat is

moving, not the direction in which the boat is pointing. If the

boat is drifting backward or sideways due to a current or

wind, the Radar overlay may not perfectly align with the chart

data. This situation should be avoided by using boat-heading

data from an electronic compass.

If the boat heading is based on data from a magnetic heading

sensor or an automatic pilot, the heading data could be

compromised due to incorrect setup, mechanical malfunction,

magnetic interference, or other factors. If the heading data is

compromised, the Radar overlay may not align perfectly with

the chart data.

Showing the Radar Overlay

The Radar overlay displays data based on the most recently

used radar mode.

Select Radar > Radar Overlay.

The radar picture appears in orange and overlays the

Navigation chart.

Stopping the Transmission of Radar

Signals

From the Radar screen, select Menu > Radar to

Standby.

Optimizing the Radar Display

You can adjust the radar display settings for reduced clutter

and increased accuracy.

NOTE: You can optimize the radar display for each radar

mode.

1Select a radar range (page 18).

2Restore the default value of the gain setting (page 18).

3Adjust the gain setting manually (page 18).

Range of Radar Signals

The range of the radar signal indicates the length of the

pulsed signal transmitted and received by the radar. As the

range increases, the radar transmits longer pulses in order to

reach distant targets. Closer targets, especially rain and

waves, also reflect the longer pulses, which can add noise to

the Radar screen. Viewing information about longer-range

targets can also decrease the amount of space available on

the Radar screen for viewing information about shorter-range

targets.

Radar Gain and Clutter

Automatically Adjusting Gain on the Radar Screen

Auto is the default value for the gain setting. The automatic

gain setting for each Radar mode is optimized for that mode,

and may differ from the automatic gain setting used for

another mode.

NOTE: Depending upon the radar in use, the gain setting

configured for use in one radar mode may or may not be

applied to other radar modes or to the Radar overlay.

From a Radar screen or the Radar overlay, select Menu

> Gain > Auto.

The chartplotter sets the gain automatically once, based

on average conditions, the range of the radar signal, and

the selected radar mode. The chartplotter does not

readjust the gain automatically in response to changing

conditions.

Manually Adjusting Gain on the Radar Screen

For optimal radar performance that accounts for actual

conditions, you can manually adjust the gain.

NOTE: Depending upon the radar in use, the gain setting

configured for use in one radar mode may or may not be

applied to other radar modes or to the Radar overlay.

1From a Radar screen or the Radar overlay, select Menu

> Gain.

2Select Up to raise the gain, until light speckles appear

across the Radar screen.

18 Radar

Data on the Radar screen is refreshed every few

seconds. As a result, the effects of manually adjusting the

gain may not appear instantly. Adjust the gain slowly.

3Select Down to lower the gain until the speckles

disappear.

4If boats, land, or other targets are within range, select

Down to lower the gain until the targets begin to blink.

5Select Up to raise the gain until the boats, land, or other

targets appear steadily lit on the Radar screen.

6Minimize the appearance of nearby large objects, if

necessary.

7Minimize the appearance of side-lobe echoes, if

necessary.

Minimizing Nearby Large-Object Interference

Nearby targets of significant size, such as jetty walls, can

cause a very bright image of the target to appear on the

Radar screen. This image can obscure smaller targets

located near it.

NOTE: Depending upon the radar in use, the gain setting

configured for use in one radar mode may or may not be

applied to other radar modes or to the Radar overlay.

1From a Radar screen or the Radar overlay, select Menu

> Gain.

2Select Down to lower the gain until the smaller targets

are clearly visible on the Radar screen.

Reducing the gain to eliminate nearby large-object

interference may cause smaller or distant targets to blink

or disappear from the Radar screen.

Minimizing Side-Lobe Interference on the Radar Screen

Side-lobe interference may appear to streak outward from a

target in a semi-circular pattern. Side-lobe effects can be

avoided by reducing the gain or reducing the radar range.

NOTE: Depending upon the radar in use, the gain setting

configured for use in one radar mode may or may not be

applied to other radar modes or to the Radar overlay.

1From a Radar screen or the Radar overlay, select Menu

> Gain.

2Select Down to lower the gain until the semi-circular,

streaked pattern disappears from the Radar screen.

Reducing the gain to eliminate side-lobe interference may

cause smaller or distant targets to blink or disappear from

the Radar screen.

Adjusting Sea Clutter on the Radar Screen

You can adjust the appearance of clutter caused by choppy

sea conditions. The sea clutter setting affects the appearance

of nearby clutter and targets more than it affects the

appearance of distant clutter and targets. A higher sea clutter

setting reduces the appearance of clutter caused by nearby

waves, but it can also reduce or eliminate the appearance of

nearby targets.

NOTE: Depending upon the radar in use, the sea clutter

setting configured for use in one radar mode may or may not

be applied to other radar modes or to the Radar overlay.

1From a Radar screen or the Radar overlay, select Menu

> Noise Rejection > Sea Clutter > Presets.

2Select a setting that reflects the present sea conditions.

3Select Menu > Noise Rejection > Sea Clutter.

4Select Up or Down to adjust the appearance of sea

clutter until other targets are clearly visible on the Radar

screen.

Clutter caused by sea conditions may still be visible.

Adjusting Rain Clutter on the Radar Screen

You can adjust the appearance of clutter caused by rain.

Reducing the radar range also can minimize rain clutter

(page 16).

The rain clutter setting effects the appearance of nearby rain

clutter and targets more than it effects the appearance of

distant rain clutter and targets. A higher rain clutter setting

reduces the appearance of clutter caused by nearby rain, but

it can also reduce or eliminate the appearance of nearby

targets.

NOTE: Depending upon the radar in use, the rain clutter

settings configured for use in one radar mode may or may

not be applied to other radar modes or to the Radar overlay.

1From a Radar screen or the Radar overlay, select Menu

sensor or temperature-capable transducer that is

connected to the chartplotter.

2Measure the water temperature using a different

temperature sensor or a thermometer that is known to be

accurate.

3Subtract the water temperature measured in step 1 from

the water temperature measured in step 2.

This is the temperature offset. Enter this value in step 5

as a positive number if the sensor connected to the

chartplotter measures the water temperature as being

colder than it actually is. Enter this value in step 5 as a

negative number if the sensor connected to the

chartplotter measures the water temperature as being

warmer than it actually is.

Auto Guidance Line Configurations

CAUTION

The Safe Depth and Safe Height settings influence how the

chartplotter calculates an Auto Guidance line. If an area has

an unknown water depth or an unknown obstacle height, the

Auto Guidance line is not calculated in that area. If an area at

the beginning or the end of an Auto Guidance line is

shallower than the safe water depth or lower than the safe

obstacle height, the Auto Guidance line is not calculated in

that area. On the chart, the course through those areas

appears as a gray line. When your boat enters one of those

areas, a warning message appears.

NOTE: Auto Guidance is available with premium charts, in

some areas.

You can set the parameters the chartplotter uses when

calculating an Auto Guidance line.

Shoreline Distance: Sets how close to the shore you want

the Auto Guidance line to be placed. The Auto Guidance

line may move if you change this setting while navigating.

The available values for this setting are relative, not

absolute. To ensure that the Auto Guidance line is placed

the appropriate distance from shore, you can assess the

placement of the Auto Guidance line using one or more

familiar destinations that require navigation through a

narrow waterway (page 28).

Adjusting the Distance from Shore

CAUTION

The Auto Guidance feature is based on electronic chart

information. That data does not ensure obstacle and bottom

clearance. Carefully compare the course to all visual

sightings, and avoid any land, shallow water, or other

obstacles that may be in your path.

NOTE: Auto Guidance is available with premium charts, in

some areas.

The Shoreline Distance setting indicates how close to the

shore you want the Auto Guidance line to be placed. The
