1. Activate the product in an area without large buildings to improve
GPS reception.
For commercial purposes, the GPS has an average range error of more than
15 metres and the range error could be more than 100 meters depending on
environmental conditions like buildings and roadside trees etc.
2. The temperature range for optimum operation of the GPS receiver in
your car is -10 ~ 50°C.
3. When using the product for the first time or after a long period (more
than three days), it may take a little longer to recognise your current
location.
It may take between five and thirty minutes to get GPS reception.

signal are installed in the vehicle e.g. other GPS devices including certain
types of wireless activated alarms, MP3 and CD players and camera
alarms using GPS.
4) If you are using a receiver connected by a cable, electrical interference can
be avoided by simply changing the location of the receiver (antenna).

such as under a bridge or raised roadway, in a tunnel, an underground
roadway or parking area, inside a building or surrounded by high-rise
buildings.
6) If GPS signal reception is poor, it may take longer to locate your current
position when the vehicle is moving than when it is stationary.
