I messed with it, all day, at work. Connected the car to the internet, tried several starts/shutoffs, and even tried a master reset. Ended up finding a write-up on Google. Did a hard reset by pulling the fuse, letting it sit for a couple minutes, then putting it back in. Started the car, did the Sync maintenance update, shut the car off, then turned it back on. Everything seems to be working ok, now. I don't even want that Sirius crap in there. Wish I could delete it out of the system. Just one more thing to break.
