My media player has been working fine with tracks from my iPod until recently. The car can read the tracks and create a library but refuses to play anything, even though the dash display shows the track that is supposed to be playing. All voice controls and steering wheel controls work correctly. Also when I disconnect the iPod I can still select media player as a source. I didn't update the iPod, it just stopped playing through the car and works fine with headphones. Help pls.
