Most of iphone car kit or credles I am seeing are windshield or deshboard mounths. I need something that is not bulky and ugly that slides through somewhere below of idrive and has a charger/Audio dock and rotates freely at the same time. I am going to use iPod integration wire as a charger/ audio source. I have to use navigation sometimes and need it at this hight to get GPS signal. I saw Dock-spec credle that is too low for me and it does not rotate.
Anyone knows where I can get that kind of iPhone credle/charger?
Thanks
