Module, Radio Receiver: Operation

The radio becomes operational when it receives a wake up signal over the Controller Area Network B data bus indicating the status of the ignition switch is ON or Accessory. For additional information on the operation of the vehicles radio/media system in the vehicle, see the heading for the appropriate audio system option in the User Guide or the Owner Manual. See the Uconnect web site (https://www.driveuconnect.com/  ) for more information, or refer to the Owner's link on the vehicle brand web site for copies of those publications.

The radio uses a roof mounted antenna for AM/FM signal reception and, depending upon vehicle optional equipment, an instrument panel mounted Global Positioning System (GPS) antenna that can receive GPS signals.

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

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, switched ignition feed, CAN circuits, software and hardware for any concerns.
