I just did the 1.0 -> 2.2 with nav update. Everything worked seamlessly. Phew!
I also ordered the Ford part HC3Z-19A387-B instead of the Lincoln part GJ7Z-19A387-B in order to get the blue LED... According to the dealer, the Ford part is on backorder until mid-February. To me, I'd rather have the Ford part, but I'm just picky. It's too bad Apple requires their stupid authentication chip in everything. I'd rather not have spent $60 just to get CarPlay, but oh well.
