Has anyone plugged their Ipod into the USB and got it to work? I have tried 3 different Ipods and can't get any of them to play. I have read the instructions and played along as pointed out but still no luck. On the menu screen on the stereo it just says "Loading" but it never will play or even recognize any of my Ipod's. Bad unit? Unit not capable of interacting with an Apple product? Looking for suggestions.
