Colors on the Screen
When a route has been planned, it will be highlighted
on the screen in blue. If you have set a waypoint(s) for
your route, the colors on the screen will change. The
highlighted route to the next waypoint/destination will be
blue. All highlighted routes to further
waypoints/destinations will be maroon.
Different colors are also used to distinguish between
interstate freeways, state highways, county roads,
major streets and secondary streets. Highways will be
shown as a thicker line than a general street will.
Global Positioning System (GPS)
The Navigation System determines the position of your
vehicle by using satellite signals, various vehicle
signals and map data from the map DVD.
The Global Positioning System (GPS) locates the
current position of your vehicle using signals sent by the
United States Department of Defense GPS satellites.
GPS will appear green on the screen if the satellite
signal is received. GPS will be gray if no signal is being
received. See Symbols on page 2-9 listed previously
in this section for more information.

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.
The system may not be available or interference may
occur if any of the following are true:
•
Signals are obstructed by tall buildings, large trucks
or a tunnel.
•
Metallic objects are located on the dashboard.
•
Satellites are being repaired or improved.
•
After-market glass tinting has been applied to the
vehicle's windshield.
Notice: Aftermarket glass tinting with metallic
material will interfere with the system's ability to
receive GPS signals and cause the system to
malfunction. You might have to replace the rear
window to correct the problem. The repairs would
not be covered by your warranty. Do not apply
aftermarket glass tinting with metallic material to
the rear window of your vehicle.
If you are experiencing a problem, see Vehicle
Positioning on page 2-35 and Problems with Route
Guidance on page 2-36 following for more information.
