PRINCIPLES OF GPS
Your system directs you based on information derived from global
positioning satellites, road maps stored on the hard disk drive, sensors in
your vehicle and the desired destination. The system compiles all
necessary information to guide you to your selected destination. Space
satellites determine the vehicle’s current location and transmit position
and time signals to your car. If the vehicle has been parked for a long
period of time, the navigation function may be temporarily unresponsive.
The navigation system will operate reliably again once GPS reception is
available for a few minutes.
LIMITED GPS RECEPTION
System performance may be adversely affected if GPS reception is
interrupted or interference occurs over a distance of several miles. The
following are possible causes for GPS reception being interrupted. If the
vehicle is:
• In multi-story parking garages
• In tunnels and under bridges
• Inside or in between buildings
• By forests or tree-lined avenues
• In heavy rain showers and thunderstorms
• In valleys and in mountainous regions
• Roads under cliffs
Ensure that you do not have any metal objects on the dashboard and
that if your windows are tinted, they use non-metal tinting instead of
metal oxide tinting. Both of these factors can also interrupt GPS
reception.
SYSTEM LIMITATIONS
Cold temperature start: When operating the system below 32° F
(0°C), the display screen requires a 2–3 minutes warm-up time to
achieve maximum brightness.
Other conditions: When calculating a route, the system doesn’t take
into consideration any of the following conditions:
• Traffic Conditions
• Weather Conditions
• Driving Habits
