I searched for a stereo that was iphone compatible. I read in lots of places that the Alpine iDA-X001 didnt work properly with it. A local shop convinced me it did....I have had it installed for three months now and it works a treat. The blue tooth only works for the making calls via a hands free. The ipod part works with a USB cable in the glove box. All the play lists work and the contact lists.....so far the only problem I have had is that a couple of times I have had to re register the iphone with the head unit - takes 10 seconds. Have to say that I am very happy with it. 8)
