Hi. Ive had the same problem with mine (twice now)! Disconnect you car battery, have a song playing on your ipod with earphones connected only (dont have it plugged into the car), re-connect the car battery, turn on the Radio, select it so it says aux, then re-connect the ipod to the car (with the song still playing). It works for me. (only happens when ive had my ipod connected to my computer)
