Thanks for the questions. I have not tried an ipod of any kind, only iphones. And I have tried Airplane mode but the problem still persisted. BUT, I have used a usb stick with the exact same tracks and it sounds totally fine. So I would think that it has something to do with the iphone. You'll probably say well just use the usb stick, but my phone is always synced with my music and I hate having to constantly pull my usb stick and copy the latest music I have. It's certainly an option, but I was hoping to just get the iphone to work.

Forgot to respond to sophomore, you're right, I could just use the Aux method, but I hate having that cord running all over the place. I like how the usb port is hidden. It is also a lot easier to control the music using the the steering wheel controls, I just put it on random and change songs using the steering wheel. Also much safer.
