I have the factory ipod dock and I think it's pants. I have done the play lists thing but I still have a hard job finding tracks and albums on my nearly full 80gb Ipod. Can I downgrade to just the AUX in system and just use the IPod that way? Anyone done this? where does the AUX cable plug into, is it at the back of the head unit? I have searched but didn't find what I was after.
