I've had this unit in my car for a few months now with no problems whatsoever. The other day without warning it stopped playing tracks from my ipod. The ipod itself works fine on its own, I've tested it. The unit accesses the ipod and displays the track details but it just won't play, it's like it's on pause but it isn't. Also, when using the search facility I can no longer push the joystick thing to the right to access the A-Z listing. I wondered whether it was something to do with the cold weather but that's ridiculous, it's not that cold.
