iPhones have had trouble with every ford I have owned. The sync guy at the dealer told me this is known. It is not entirely incompatible, by the sync system get loaded with 'corrupt files' over time. When u bring it in for service they can refresh it, deleting the files but also your settings
I have an iPhone 4S with iOS6.0. I was so excited that I would be able to text with sync.
Well, not so much. After many attempts, deleting the profiles on the phone and car, no luck.
I have heard if you have the iPhone 5, then it's possible. Also with the newer MFT it my be possible, but not in my 2011 with my 4S phone.
Oh we'll. There's always Siri.
I just tried it with my iPhone 5. I got further than before, I don't get the unsupported message anymore but, when I try to send it just says send failed. It appears that it works about as well as everything else with Sync.
