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. A color touchscreen electronic display in the Radio Receiver Module (RRM) 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.

This navigation system provides visual guidance through dynamic maps, 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 further detail elsewhere in this service information:

• Body Control Module  - The Body Control Module (BCM) is located on the instrument panel structural support within the passenger compartment, where it is concealed behind the instrument panel to the left of the steering column. 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 .
• Left Steering Wheel Switch Pod  - The left steering wheel switch pod is located in the left horizontal spoke of the steering wheel. This switch pod contains the Uconnect™ Voice Recognition (VR) switch button and the Uconnect™ Phone switch buttons of the Uconnect™ Hands-Free Phone system. Refer to SWITCH, EVIC CONTROL, DESCRIPTION .
• Microphone  - A microphone is integral to the overhead console and roof lamp unit 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 .
• Radio Receiver Module  - The RRM is located within the instrument panel and is the primary component of the hands free phone system in this vehicle. Depending upon selected vehicle optional equipment the RRM may include a microcontroller, a Bluetooth™ transceiver, a navigation module, flash memory and sophisticated Advanced Speech Recognition (ASR) input capability through VR software. The ASR software includes many different available languages. Each vehicle is equipped with a list of available languages, which are made available from the factory based upon languages most commonly used for the market destination. Refer to RADIO, DESCRIPTION .

The RRM also contains a microcontroller and programming that allows it 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 .

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.
