I've been looking for the cable online but I got scared with a few comments that said the necessary cable depended on the Audi model and the Ipod model.

I guess there's a blue one and a black one?!
Does anybody know the difference?

I just dont want to buy the wrong one, you know?

Thanks a lot for any reply.
Btw, is it too soon to have an A1 section here in the forum?

Cheers,
kravi
