Is anyone else having a problem using your 4S with bluetooth? Just purchased a '14 XTS Premium and the bluetooth keeps disconnecting and reconnecting every few minutes. It really starting to tick me off; never happening once in the Hyundai I replaced. I called the Infotainment line, and they had me delete the connection on both phone and car, and then reconnect...same issue. just waiting for a callback, but thought I'd ask if this was a common issue?
