This TSB applies to 2011-2012 Mitsubishi Outlander and Lancer based vehicles equipped with Real Time Traffic (RTT) feature (Navigation MZ360390EX).
If a customer reports that the system won’t find the feature or if no stations are available, there could be one of two causes: RTT is not available in all areas, or it is possible that the A-3 wiring harness was not installed.
First determine if RTT is available for the area in question. If so, be aware that the harness is included with the navigation unit, but not the installation kit. Confirm that it is properly installed and retest before replacing the unit. Refer to the installation instructions on the MDL for details.
