The position of the vehicle is determined by using satellite signals, various vehicle signals, and map data.
At times, other interference such as the satellite condition, road configuration, condition of the vehicle, and/or other circumstances can affect the navigation system's ability to determine the accurate position of the vehicle.
The GPS shows the current position of the vehicle using signals sent by the GPS Satellites. When the vehicle is not receiving signals from the satellites, a symbol appears on the map screen.
This system might not be available or interference can occur if any of the following
are true:
• Signals are obstructed by tall buildings, trees, large trucks, or a tunnel.
• Satellites are being repaired or improved.
