This has happened to me a few times before. I deleted my 4S and did a fresh pair and it fixed the issue. Since that didn't seem to work for you, I suggest you do a master reset of MFT. Remember to disconnect everything before you do (this includes the nav sd card, usb, etc.). That should fix it. If it doesn't, try pulling the fuse for MFT. If that doesn't work, make an appointment with your dealer.
