The GPS shows the current position of your vehicle
using signals sent by the GPS Satellites of the
United States Department of Defense. When your
vehicle is not receiving signals from the satellites,
a symbol will appear on the map screen. Refer to
Symbols on page 2-8.
This system may not be available or interferences
may occur if any of the following are true:
•
Signals are obstructed by tall buildings, trees,
large trucks, or a tunnel.
•
Objects are located on the rear shelf.
•
Satellites are being repaired or improved.
•
After-market glass tinting has been applied to
the vehicle's rear windshield.
Notice: Do not apply after-market glass tinting to
the vehicle's windows. Glass tinting will interfere
with the system's ability to receive GPS signals
and cause the system to malfunction. You might
have to replace the window to correct the problem.
This would not be covered by your warranty.
For more information if you are experiencing a problem,
see If the System Needs Service on page 2-77 and
Problems with Route Guidance on page 2-76.

or when the vehicle is turning on a turn table in
a parking lot.
•
The vehicle is entering and/or exiting a parking lot,
garage or a lot with a roof.

The GPS signal is not received.
