DESCRIPTION
| 1 - Radio |
There are three radios available in this vehicle, Uconnect® 3 with 5 inch display, Uconnect® 4 with 7 inch display, and Uconnect® 4C NAV with 8.4 inch display. Each radio has a distinct chassis design and is identified by a sales code. Some markets use a Uconnect® 4 NAV with 8.4 inch display in place of the Uconnect® 4C NAV with 8.4 inch display.
Hardwired circuitry connects the radio to the electrical system of the vehicle. These hardwired circuits are integral to several wire harnesses, which routes throughout the vehicle and retained by many different methods. These circuits may be connected to each other and to the vehicle electrical system through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds. For proper wire repair, refer to: WIRE SPLICING and connector repair procedures refer to: REMOVAL and INSTALLATION .
The radio cannot be adjusted or repaired. If the radio is damaged or ineffective, it must be replaced.
OPERATION
The Security Gateway Module (SGW) is the Controller Area Network (CAN) gateway between the radio, telematics modules, Data Link Connector (DLC) and the other vehicle CAN modules. An SGW failure could prevent the radio from powering up, telematics module from communicating or a scan tool from communicating with the vehicle. For additional information on the SGW, Refer to MODULE, SECURITY GATEWAY (SGW), DESCRIPTION AND OPERATION .
The radio receives fused B+ from a fuse located in the Power Distribution Center (PDC) and is grounded through a circuit in the body wire harness that is secured to the sheet metal behind the passenger kick panel at all times.
The radio becomes operational when it receives a wake up signal over the CAN IHS data bus indicating the status of the ignition switch is ON or Accessory. For additional information on the operation of the radio or media system in the vehicle, review the heading for the appropriate audio system option in the User Guide or the Owner Manual. Consult the Uconnect® web site (https://www.driveuconnect.com/ ) for more information, or refer to the For Owners link on the vehicle brand web site for copies of those publications.
The Security Gateway Module (SGW) is in the audio and telematics CAN 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.
The radio uses a fender mounted mast antenna for AM/FM signal reception and, depending upon vehicle optional equipment, a middle sport bar mounted combination antenna that can receive Global Positioning System (GPS) and satellite radio signals. For additional information about the audio system and its components, Refer to: AUDIO/VIDEO/ENTERTAINMENT/CONNECTIVITY - DESCRIPTION AND OPERATION .
Certain markets use a windshield mounted Digital Audio Broadcast antenna and module for reception and amplification of digital audio broadcast radio signals.
Depending upon the audio system options, the radio can play audio 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) port, a Universal Serial Bus (USB) port or through wireless Bluetooth® audio streaming. Refer to the Uconnect® web site (https://www.driveuconnect.com/ ) for compatibility information.
USB devices (for example, camera memory USB adaptors and others, excluding Apple products) must comply with the Mass Storage Device (MSD) standard. This remote USB port can provide power to the inserted device.
The radio is used by the Rear View Camera (RVC) system to display the images projected by the RVC. For additional information about the RVC system without FVC, For additional information about the RVC with FVC. Refer to: AUDIO/VIDEO/ENTERTAINMENT/CONNECTIVITY - DESCRIPTION AND OPERATION . Refer to: CHIME/BUZZER/DRIVER ASSIST - DESCRIPTION AND OPERATION .
The radio supports the Navigation system, if equipped, by displaying the data from the GPS satellites on the radio screen. For additional information about the Navigation system. Refer to: NAVIGATION/TELECOMMUNICATION - DESCRIPTION AND OPERATION .
The radio is also used as the compass display for vehicles equipped with either the radio and integral compass or the stand alone compass module for radios that do not have the integral compass. If the vehicle did not have a radio when assembled at the factory, then the compass module data is displayed in the Instrument Panel Cluster (IPC). For additional information about the stand alone compass module, Refer to: INSTRUMENT CLUSTER - DESCRIPTION AND OPERATION .
