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.
This 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. |
| • | Aftermarket 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 windshield to correct the problem. The repairs would not be covered by your warranty. Do not apply aftermarket glass tinting with metallic material to the windshield of your vehicle.
Do not place metallic objects on the vehicle's dashboard, as they may 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.
