On my 2014 ST, The only thing that does not work, is that my text messages don't show up on the Ford sync nav screen. It has a message that reads "Text messages are not suported by this phone" I have a Apple I phone 4 S. I did call Ford to make sur that my phone settings and operating system was compatible, and it is. I also called Apple and whent over everything with them. I also asked the dealer about it. They said just that sometimes it does not seem to work. So any one have some suggestions?
