174  Using GPS
11.1  Guidelines and Preparation for Using GPS
 
Do not operate the GPS system while driving. The plotted GPS route 
is only for driving reference. It should not interfere with actual driving 
behavior.
 
Please use the GPS system cautiously. Users shall be liable for any 
damages resulting from negligent operation of the system.
  The GPS signal cannot pass 
through solid non-transparent 
objects. Signal reception may be 
affected by obstructions such 
as high-rise buildings, tunnels, 
bridges, forests, weather (rainy or 
cloudy days), etc. If the vehicle’s 
visor contains metal, it will be 
difficult for the GPS signal to 
pass through. For better signal 
reception, connect your device to 
an external GPS antenna.

  Wireless communication products (such as mobile phones or radar-
detecting devices) may interfere with the satellite signal, resulting in 
unstable signal reception.
  The Global Positioning System (GPS) is built and operated by the US 
Defense Department. The Department is responsible for the accuracy 
and maintenance of the system. Any changes that the Department 
makes may affect the accuracy and function of the GPS system.
  Do not leave your device in a vehicle or expose the device to direct 
sunlight to avoid overheating the battery, which could pose damage 
to the device or risk to the vehicle.
