Description
The Radio Entertainment Telematics Module (ETM) manages the radio, hands-free, navigation, and satellite functions of the vehicle. The ETM 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 ETM 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 ETM uses a roof mounted antenna for AM FM signal reception; and depending upon optional equipment, a roof mounted combination antenna that can receive global positioning system (GPS) and satellite radio signals
