Yes, it would seem logical, if I knew that was what caused it to stop working. I didn't know if maybe others had experienced a similar problem, and may know how to fix it. The last time it worked, the HU was in another vehicle and it was probably 8-10 months ago. I mentioned the upgrade so that other users wouldn't have to ask what version I was running, not because I was trying to diagnose my problem.
sorry for the confusion.
