I've had this one for about 2 years now for my iphone, works great! It plugs into the CD changer socket at the back of radio unit, (mine's a 2008 atx), no soldering or rewiring, just plug-n-play. 1 cable and you can control the tracks and volume from the steering wheel and it charges the iphone as well. But you need a chinese friend to help you: http://item.taobao.com/item.htm?spm=a230r.1.14.320.Ytscif&id=4699212838 If you want USB or other input, try this one: http://item.taobao.com/item.htm?spm=a230r.1.0.0.Vrifkd&id=20229975477
