Rear Display(s) Global Positioning System (GPS) 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 current position of the vehicle using signals sent by the GPS Satellites of the United States Department of Defense. When the vehicle is not receiving signals from the satellites, a symbol appears on the map screen. Refer to Global Positioning System (GPS) on page 7‑96. Press the Rear Display(s) screen button to allow the choice of sources for rear display between front disc, rear aux, or usb, if connected. 12/24 Format: Select the 12 screen button for standard time; select the 24 screen button for military time.
