H. Helpful tips
Some vehicles using heavy metallic sun protecting coating on windshield may affect GPS signal reception.
Streets with high rising buildings may affect GPS signal reception.
Tunnel and indoor parking garage may affect signal reception.
In general, GPS signal reception best in open space where it can see clear sky. Weather condition will also affect
GPS reception – rain & snow contribute to worse sensitivity.
Low battery status may affect signal reception.
This device outputs coordinates data every second, therefore the actual position and the position shown on your map
may have slight time delay. This may happen when you drive at higher speed or make a turn around a corner.
For the device not in use over several days, allow it 1~3 minutes to obtain satellite constellation information and fix
your position, this is called “Cold Start”. Upon battery replacement, GPS device will do Cold Start again.
If your device can not fix position for more than 20 minutes, please change to another location with open space and
then try again.
