I went to replace my 3 yr old alpine headunit, the face does not always work when it opens. So anyway, I went to a local high end electronics store (ABT) and the salesperson was nice enough to try my iphone with the newer iDA-X001...it was a definate NO GO. there were errors on both the iphone, and the head unit... good news is, the bluetooth add on worked flawlessly. so for me, I will leave my 80 gig ipod in the glovebox, and let the iphone work just as a phone
