is it possible to get a cable that allows you to control the music through your ipod, but also plugs into the back of the head unit, and charges the ipod. Blue&me is rubbish, I've got a 60gb ipod and by the time it loads onto the headunit, I am where ever I need to be. I currently have a FM transmitter, but I would like something that charges it and have all the cables hidden away....Thanks
