I think the iPod cable is pooched. The dealer installed it with the deck so it's probably a knock-off lol.
What happens is if I plug in my iphone or an itouch it says 'ready' on the deck but nothing plays.
The message changed on my phone from saying 'airplane mode switch' to just 'device not supported for charging'.
If I plug the iphone in then turn on the car for power, the deck remains black and will not power up at all.
My phone also goes wonky and I have to reset it for it to work properly again after plugging it in.
