The Navigation System determines the position of the vehicle by using satellite signals, various vehicle signals and map data.
At times, other interferences such as the satellite condition, road configuration, 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 accurate current position of the 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 appears on the map screen.
This system may not be available/or interference may occur if:
| • | Signal obstructions are caused by tall buildings, large trucks, tunnels, |
| • | objects are located on top of the instrument panel, |
| • | satellites are being repaired or improved, and cannot send signals. |
| • | after-market glass tinting has been applied to the vehicle's windows. |
Notice: Do not apply after-market glass tinting to the vehicle's windows. Glass tinting interferes with the system's ability to receive GPS signals and causes the system to malfunction. The window might have to be replaced to correct the problem. This would not be covered by the warranty.
If experiencing a problem, see If the System Needs Service and Problems with Route Guidance.
