Navigation/Telecommunication (Service Information): Description: Navigation

A factory-installed satellite navigation system based upon the Global Positioning System (GPS) is an available option on this vehicle. Each system provides the vehicle operator with both visual and audible guidance to a chosen destination. The 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 RRM disassociated color touchscreen electronic display, called the Display Screen Module (DSM), 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 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:

The IPC, DSM and the RRM each contain a microcontroller and programming that allow them to communicate with each other and other 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 is damaged or ineffective, that component must be replaced. The external combination antenna can be repaired separately from the RRM. The navigation system software as well as the map data is flash programmable through the Universal Serial Bus (USB) port.
