Global Positioning System Module (GPSM)
WARNING: This page is about a different car, the 2013 Lincoln MKX and 2013 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
For vehicles without navigation, the GPSM provides vehicle location for real-time traffic reports and re-routing, and for identifying vehicle location in the event of a collision.
For vehicles with navigation, the GPSM acts as the antenna for the navigation system.
The vehicle location information is broadcast to the APIM over the MS-CAN.
