MyTouch is bug-gy to say the least. My 2013 SHO hasnt worked right from day one, but I updated it this weekend it seems to finally be working. My Sync on the 2011 Raptor has been a bit of a nuisance as well.
Ford knows they have a crap solution here. They took a MAJOR hit in Consumer Reports reliability rating solely based on the Sync and MyTouch issues their cars are having. It seemed a good idea at the time, and when it works, its okay, but I never would have tied my system to a Microsoft product. (And I used to work for them)
