“I just bought this stereo system, and my 80gb ipod will not work with it consistently. Do I need some accessory to make it work? Thanks! 8 out of 10 times it will not work. I have tried turning the unit on and off, taking the ipod on and off of the dock, and opening and shutting the dock. I get the message in the display "NO DEVICE." And then, a very few times, the message " CONNECTING" will display and then the stereo will play the Ipod. Help! Do I need to buy something else to make this work (like a special cradle for the Ipod?)? I do not have a case on the Ipod. Thanks!”
