Theory Of Operation
The Radio manages the hands-free, navigation, and satellite functions of the vehicle. The Radio becomes operational after receiving a wake up signal over the CAN-IHS data bus indicating the status of the ignition switch is On. Depending upon audio system options, the Radio can play audio from many different media sources, such as the 3.5 millimeter auxiliary (AUX) port, a universal serial bus (USB) port or through wireless Bluetooth™ audio streaming. The Radio is capable of using AM/FM, Cellular, Global Positioning System (GPS) and Satellite Radio signals depending upon the audio system/vehicle configuration.
Make sure any serviced speakers are similar to the one being removed. The Radio uses the vehicle build configuration data (based upon sales code) to determine the audio configuration.
