Global Positioning System (GPS)
The navigation system determines the position of your
vehicle by using satellite signals, various vehicle signals,
and map data.
The Global Positioning System (GPS) locates the
current position of your vehicle using signals sent by the
United States Department of Defense GPS satellites.
While your vehicle is receiving signals from these
satellites, the GPS symbol will not appear on the map
screen. See Symbols on page 4-42 for more information
on the GPS symbol.
However, at times, other interferences such as the
satellite condition, road configuration, the condition of
the vehicle, and/or other circumstances can interfere
with the system’s ability to determine the accurate
position of the vehicle. This is when the GPS symbol
will appear on the map screen.
This system may not be available/or interferences may
occur if any of the following are true:
•
Signal are obstructed by tall buildings, large trucks,
or a tunnels.
•
Satellites are being repaired or improved.
•
Objects are located on the rear shelf.
•
After-market glass tinting has been applied to the
vehicle’s windows.
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.
If you are experiencing a problem, see Vehicle
Positioning on page 4-49 or Problems with Route
Guidance on page 4-50 for more information.
