Bluetooth audio streaming pauses/stutters/skips to the next track intermittently. Problem can be quite intermittent or constant. Also get an intermittent message saying that Sync has lost contact with the phone and is trying to re-pair, but in reality the phone is still paired. Bluetooth phone features otherwise work perfectly including phone calls. This with an iphone 5, iOS 6.1.3, paired with a brand new 2013 Ford F150 with Nav/Sync/MyFord touch software version 3.5.1. Also paired my wife's iphone 5, same problem. What I've tried:soft and hard reboot of the iphone. Deleting and re-pairing the phone. Troubleshooting with MyFord customer service, their opinion is it's an iOS issue. Anyone else having similar issues? Anyone have any suggestions?
