Section 307 (Navigation/Telecommunication (Service Information)): Description: Navigation

WARNING: This page is about a different car, the 2014 Jeep Patriot and 2014 Jeep Compass. However, it is still accessible from the selected car via links, so may be relevant.

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) (also known as the radio or the head unit) provides a graphical interface for programming, searching for and selecting destinations.

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:

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, OPERATION .
Radio Receiver Module - The Radio Receiver Module (RRM) (also known as the radio or the head unit) is located within the instrument panel and is the primary component of the navigation system in this vehicle. In vehicles equipped with the optional navigation system the RRM includes a microcontroller, a navigation module and flash memory. 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 - B (CAN-B) 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 a Universal Serial Bus (USB) port.
