I have a Sony CDX-M600 deck and it has the red/white inputs on the back of the deck. I was so stoked because that meant that I could use my iPod with my deck, but when I'm plugged into the back I can't seem to switch to that channel to hear the iPod. Any ideas? I have a good feeling this input is intended for the CD Changer bus, but I'm at a loss. Any ideas?
