GPS Antenna
WARNING: This page is about a different car, the 2013 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
The GPS antenna is integral to the satellite radio antenna and is only present on vehicles with navigation. The location signals are sent to the ACM via a coaxial cable. A GPS/SDARS antenna splitter is used to provide separate satellite radio and Global Positioning System (GPS) inputs to the ACM.
