I'll be getting into the dealer this Tue, but I wanted to give an update if someone else runs into this. Screen stayed dark after the master reset, which obviously is a pain in the ass, and you lose many functions. I was assuming the heat/ac would not work. They do work, you just have no way of knowing what it's set at, except for feel. Just for the hell of it, when I was driving Friday, I did the soft reset. The screen did come back up, but that Sync update crap also came up right away on the screen, so I hit the "Ask me later option". If you were on a trip at least you could get your screen back and have most of your functions back, until you can get it fixed.
