Description And Operation: Navigation: Description

A factory-installed satellite navigation system based upon the Global Positioning System (GPS) is an available option on this vehicle. Depending upon the optional touchscreen radio selected for the vehicle, there are some variations in navigation system features available. Each system provides the vehicle operator with both visual and audible guidance to a chosen destination. An available 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 radio color touchscreen electronic display provides a graphical interface for programming, searching for and selecting destinations. In vehicles also equipped with a Uconnect® Hands Free telecommunication option, 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, while 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 navigation system includes the following major components, which are described in additional detail elsewhere in this service information:

• Body Control Module  - The Body Control Module (BCM) is located within the instrument panel on the driver side of the vehicle. The BCM is the configuration master node for the vehicle. Refer to MODULE, BODY CONTROL (BCM), DESCRIPTION AND OPERATION .
• Combination Antenna  - For vehicles equipped with satellite audio, 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, AUDIO, DESCRIPTION AND OPERATION .
• 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 radio touchscreen unit. Refer to DESCRIPTION AND OPERATION .
• 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 the lower part of this switch pod contains the Uconnect® Voice Recognition (VR) switch button and the Uconnect® Phone switch button of the Uconnect® Hands Free Phone system. Refer to SWITCH, EVIC CONTROL, DESCRIPTION AND OPERATION .
• Microphone  - A microphone is integral to the overhead console in the headliner near the center of the upper windshield opening header panel in vehicles equipped with the Uconnect® Hands Free Phone system. Refer to MICROPHONE, DESCRIPTION AND OPERATION .
• Radio  - The radio contains the central components of the navigation system. A navigation module is internal and integral to each radio 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 AND OPERATION .

The BCM, the IPC and the radio each contain a microcontroller and programming that allows them to communicate with other electronic modules in the vehicle using the Controller Area Network - Interior High Speed (CAN-IHS) data bus. Refer to COMMUNICATION, DESCRIPTION AND OPERATION .

The navigation system components cannot be adjusted or repaired. If any of the navigation system components is damaged or ineffective, that component must be replaced. The external combination antenna can be repaired separately from the radio. The navigation system software as well as the map data is flash programmable through the Universal Serial Bus (USB) port.
