12.1 Important notices on using the GPS
GPS system structure
GPS positioning and reception
The GPS (Global Positioning System) is provided by the United States Department of Defense. Refer to the information published by
the United States Department of Defense regarding the precision of the system.

It is recommended that your car remain in an open space the first time you activate the device. GPS positioning may take more
than 5 minutes, depending on various factors such as weather conditions, surrounding environment, and strength of satellite signal.
Satellite signal reception on the G4 may be affected by poor weather condition or obstacles within your location. (i.e., being indoor/
in a high rise building/ tunnel/underground passage/forest). The system will not be able to offer positioning or navigation in such
circumstances.
The electronic map information provided by the G4 is only intended for normal references and is not to be used for obtaining high
precision topographical measurements.
Depending on the strength of satellite signal reception, it is possible that the positioning function may deviate from the actual route
you take (for example, your vehicle may appear on another route on the map). When this happens, this does not mean the system
has malfunctioned. The system will automatically rectify the actual road conditions.
Interferences of satellite signal reception may occure if you have solar window film or anti-UV glass installed on your vehicle. If so,
you can enhance signal strength by using an antenna extension during its installation.
As the map information may not be consistent with the actual road conditions, the suggested path planning offered by the G4
should only be used as references and should not affect your actual driving behavior. Please drive according to the actual road
conditions and relevant traffic regulations. If road conditions differ from the information provided by the G4, please observe the
actual road conditions.
