2.3 Helpful Tips
- It’s better to turn off the iBT-GPS when you don’t use it, or the serial Flash's
life can’t last long.
- Some vehicles having heavy metallic sun protecting coating on windshields
may affect GPS signal receptions
- Driving in and around high buildings may affect GPS signal receptions.
- Driving in tunnels or indoor park may affect signal receptions.
- In general, any GPS receiver performs best in open space where it can see
clean sky. Also weather will affect GPS reception – rain & snow contribute
to worse sensitivity.
- Low battery of a PDA or of an iBT-GPS may affect signal receptions.
- Please check the correct “COM” and “Baudrate” of your PDA.
- iBT-GPS output data updates every second, therefore the actual position and
the position shown in your map may have slight time delay. This may
happen when you drive at higher speed or make a turn around a corner.
- Note that iBT-GPS may not work indoors where it can not see the sky.
- For the 1st time you use the iBT-GPS, it will take 1 to 3 minutes to obtain the
satellite constellation information and fix your position, this is called “Cold
Start”. If you replace the battery, iBT-GPS will do Cold Start again.
- If your iBT-GPS can’t fix your position for more than 20 minutes, we
suggest you change to another spot with open space and then try again.
