I use my iPod all the time through the aux socket on my Mk1. There's no way you can get it to use the steering wheel controls via aux because it is an audio signal connector and doesn't transfer any data. You might get some joy if you can connect via bluetooth if that's available on radio and iPod. As I have an iPod classic the best I can do is shuffle through a playlist. In an aside I was doing just that for the music at a friend's party the other week, a 20 something was horrified at the archaic technology - might as well have brought a wind up gramophone.
