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 these satellites, the GPS symbol will not appear on the map screen. See Symbols for more information on the GPS symbol.
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 is when the GPS symbol will appear on the map screen.
This system may not be available/or interferences may occur if any of the following are true:
| • | Signal are obstructed by tall buildings, large trucks, or a tunnels. |
| • | Satellites are being repaired or improved. |
| • | Objects are located on the rear shelf. |
| • | 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 you are experiencing a problem, see Vehicle Positioning or Problems with Route Guidance for more information.
