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
waypoint(s) will be in maroon and from the waypoint(s)
to the final destination will be blue. Once you have
arrived at your final waypoint(s), the route to your
destination will change to blue.
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 CD.
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” 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:
D Signals are obstructed by tall buildings, large trucks
or a tunnel.
D Metallic objects are located on the dashboard.
D Satellites are being repaired or improved.
D After
-
market glass tinting has been applied to the
vehicle’s windshield.
Do not apply after
-
market glass tinting to the vehicle’s
windshield or place metallic objects on the vehicle’s
dashboard. Glass tinting and metallic objects will
interfere with the system’s ability to receive GPS signals
and may cause the system to malfunction.
If you are experiencing a problem, see “Vehicle
Positioning” and “Problems with Route Guidance”
following for more information.
