im about to get 2 12" alpine type s subs from my friend for real cheap... im interested in getting an ipod interface/adapter/connecter for my car so i can listen to the music from my ipod. It would be nice if i could control the ipod songs from the deck and steering wheel controls but i guess its not a must. Does anyone have any suggestions for which brand/model i should get. I really havent found any good ones exept for this one on ebay. It would be nice if someone could give me some feedback on their ipod interfaces for the 04 a6 2.7t s-line

thanks
