Navigation/Telecommunication (Service Information): Description: Navigation
A factory-installed satellite navigation system based upon the Global Positioning System (GPS) is an available option on models equipped with the Uconnect® 5 NAV 257 mm (10.1 in.) radio and Display Screen Module (DSM). Depending upon the market the vehicle is equipped for, some variations in navigation system features are available. Each system provides the vehicle operator with both visual and audible guidance to a chosen destination. A single premium navigation system includes such features as one-shot Voice Recognition (VR) destination entry, three dimensional city models and landmarks, digital terrain modeling, SiriusXM® Travel Link, and SiriusXM® Traffic.
A DSM color touchscreen electronic display provides a graphical interface for programming, searching for, and selecting destinations. Being equipped with a Uconnect® Hands Free telecommunication, the available navigation systems are also equipped with Advanced Speech Recognition (ASR) input capability allowing hands free operation. Each system provides visual guidance through dynamic maps with a turn-by-turn feature that can be enabled or disabled by the vehicle operator. At the same time, voice prompts through the audio system of the vehicle provide the vehicle operator with audible alerts and directions coordinated with the visual displays. The system also displays and logs valuable trip information such as speed, posted speed limit, distance, and Estimated Time of Arrival (ETA).
The premium navigation system is activated when the vehicle is shipped from the factory.
The navigation system includes the following major components, which are described in more detail elsewhere in this service information:
- Body Control Module - The Body Control Module (BCM) is located on the right cowl side inner panel within the passenger compartment, where it is concealed behind the cowl side kick panel to the right of the instrument panel. The BCM is the configuration master node for the vehicle. Refer to MODULE, BODY CONTROL (BCM), DESCRIPTION .
- Combination Antenna - The navigation module acquires GPS position data through a roof-mounted combination antenna that also receives satellite audio and cellular signals. Refer to ANTENNA, SATELLITE, DESCRIPTION .
- Electronic Vehicle Information Center - The Electronic Vehicle Information Center (EVIC) is an electronic display within the Instrument Panel Cluster (IPC). When Turn-By-Turn navigation is enabled through the EVIC Personal Settings menu, the EVIC displays turn-by-turn directions to the chosen destination supplemental to the navigation display within the RRM and DSM. Refer to CENTER, ELECTRONIC VEHICLE INFORMATION, DESCRIPTION .
- Electronic Vehicle Information Center Switch Pod - The EVIC switch pod is located in the left horizontal spoke of the steering wheel. In addition to the EVIC switch buttons this switch pod contains the Uconnect® VR switch button and the Uconnect® Phone switch button of the Uconnect® Hands Free Phone system. Refer to SWITCH, EVIC CONTROL, DESCRIPTION .
- Microphones - Stereo microphones are mounted in the headliner just above the driver and front passenger in vehicles equipped with the Uconnect® Hands Free Phone system. Refer to MICROPHONE, DESCRIPTION .
- Radio Receiver Module - The RRM contains the central components of the navigation system. In addition to a 257 mm (10.1 in.) color electronic touchscreen display, a navigation module is internal and integral to each RRM that is equipped with navigation capability. The navigation module contains all of the navigation system hardware and software. Hardware includes the GPS receiver, an electronic gyroscope, a microcontroller, and flash memory for system software and map data storage. Refer to RADIO, DESCRIPTION .
The IPC and the RRM each contain a microcontroller and programming that allow them to communicate with electronic modules in the vehicle using the Controller Area Network - Interior High Speed (CAN-IHS) data bus. Refer to COMMUNICATION, DESCRIPTION .
The navigation system components cannot be adjusted or repaired. If any of the navigation system components are damaged or ineffective, that component must be replaced. The external combination antenna can be repaired separately from the RRM. The navigation system software and the map data are flash programmable through the Universal Serial Bus (USB) port.
