Module, Radio Receiver: Operation

The radio becomes operational when it receives a wake up signal over the Controller Area Network - Interior High Speed (CAN-IHS) data bus indicating the status of the ignition is ON or Accessory. For additional information on the operation of the radio and media systems in the vehicle, see the heading for the appropriate audio system option in the User Guide or the Owner Manual in the vehicle glove box. Also see the Uconnect® web site (https://www.driveuconnect.com/  ) for more information, or refer to the Owners  link on the vehicle brand web site to view or download copies of those publications.

The radio uses an on-glass antenna screened to the backglass for AM/FM signal reception and, depending upon optional vehicle equipment, a roof mounted shark fin combination antenna that can receive GPS, satellite radio and cellular telephone signals.

Depending upon the audio system options, a radio can play music from many different media sources. The media can be played by connecting the source to the audio system via a 3.5 millimeter auxiliary (AUX) audio port or the Universal Serial Bus (USB) ports. Refer to the Uconnect® web site (https://www.driveuconnect.com/  ) for compatibility.

The radio also provides the compass direction to the Body Control Module (BCM), which in turn provides it to the Instrument Panel Cluster (IPC) to use for display in the Electronic Vehicle Information Center (EVIC).

The Security Gateway Module (SGW) is in the audio and telematics systems to provide security against certain types of attacks and threats from the scan tool, telematics and entertainment buses, which can put the rest of the vehicle's buses at risk of intrusion. The SGW lies electrically between the vehicle on one side, and the Data Link Connector (DLC), telematics and entertainment systems on the other side. The main function is to gate messages from one bus to another. The SGW monitors the B(+) feed, ignition feed, CAN circuits, software and hardware for any concerns.
