Global Positioning System (GPS)
The navigation system determines the position of your
vehicle by using satellite signals, various vehicle signals,
and map data.
At times, other interferences such as the satellite
condition, road conguration, the condition of the vehicle
and/or other circumstances can interfere with the
navigation system’s ability to determine the accurate
position of the vehicle.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 toSymbols on page 4-44.
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,
seeIf the System Needs Service on page 4-52and

information, the station’s Program Service (PS) and
Program Type (PTY) will replace the station’s frequency
on the status line at the top of the display. After about
ve seconds, if available, the PTY will be replaced
on the display by the station’s PTY name. The PTY and
PTY name may be the same or different.
If the audio system is tuned to a station that is not
broadcasting RDS information, the station’s frequency
will remain on the display. While RDS is on, the
audio system will search for a stronger station in the
network if a station gets too weak for listening.
The RDS feature relies upon receiving specic
information from RDS stations. These features will only
work when RDS information is available.
