Sgt1411, I don't know; the dealer has not gotten back to me to reschedule.
Meanwhile, here is another problem that shows up with no predicable pattern. When I start the car, or while driving, and my iPhone bluetooth is on, MFT sometimes thinks my phone is making a call. The MFT screen shows the call timer is ticking along as if I was actually on a call. However, there is not call being made or call received. I did not initiate a call on my iPhone and the phone home screen shows no call is active. Somehow MFT thinks I'm on the telephone but I'm not! While this is going on I can press the end call button on the MFT screen and it does not respond. The iPhone screen shows no call is active. I pressed the telephone icon on the iPhone and it has no affect on MFT. Then, on it's own, MFT will end the phantom call. Time line from start to end is anywhere from 10 seconds to 2 minutes.
So, I am thinking about a master reset to work out the gremlins. I hope this works. Meanwhile, I have another call into dealer service and no reply.
