Hi, I just bought a new ipod touch. I have an auxillary port and cord for my car. The sound will play, but everytime the car is shut off or the ipod is shut off, there will be no sound when it comes back on and I have to disconnect the auxillary cord from the ipod and put it back in. It then will work. Any ideas on what is going on here? I had an ipod classic before this and never had that issue.
