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.
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:
• | Signals are obstructed by tall buildings, large trucks, or a tunnel. |
• | Objects are located on the rear shelf. |
• | Satellites are being repaired or improved. |
• | After-market glass tinting has been applied to the vehicle's rear 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 rear window to correct the problem. The repairs would not be covered by your warranty. Do not apply aftermarket glass tinting with metallic material to the rear window of your vehicle.
