I've got a Dension (I think) lead that plugs into the back of the dash mounted cd changer and goes into the glove box. I can skip through tracks but not change albums or playlists, and it doesn't charge the iPod either. I have to select my playlist before plugging it in too. If I want to change albums/playlists I have to unplug it and do it on the iPod then plug it back in again. Pretty basic but it's good enough for me. When I bought the car I didn't have an iPod so didn't spec it, but will in my next car if I buy brand new again.
