"GPSM and PMI Module" were replaced today and the GPS is showing EXACTLY where my car is for the first time. They had it all day, but gave us a rental to use, and they also performed the TSB 13-5-1 DCDC Converter software update. Part number: CJ5Z-10E893-C; Description: Aerial Asy - G
Upon arriving home and plugging it in, the ring did not light up. I unplugged and plugged back in - still no light. I unplugged, opened the door and closed it, plugged it back in and the light and fan came on. Don't know if this is a result of the software update as that would be annoying. (Update: This is apparently not unknown in an Energi with a depleted battery like ours was. Typical solution is to start and shutoff the car. Mine was to open and shut the drivers door.)
Overall, glad the GPS is finally working as it should, now only the 3.5.1 left to do when it arrives - pending other issues.
