Colors on the Screen
When a route has been planned, it will be highlighted
on the screen in blue.
Different colors are also used to distinguish between
interstate freeways, state highways, county roads, major
street and secondary streets. Highways will be shown
as a thicker line than a general street.
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 the
satellites, GPS will appear on the map screen.
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.
The system may not be available or interferences 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.
•
Aftermarket glass tinting has been applied to the
vehicle’s windshield.
Do not apply aftermarket 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”
