After several attempts with more or less matching Cradles I finally found the right product. The Kensington Quick Release Holder is suitable for the Iphone 3 as well as for the 4p. As is easy gekelemmt only on the long sides, I also hope that the iPhone 5 still reinpasst :-). All buttons and even the Dock Port beleiben accessible. Several different Navis I've tried have also fitted. I prefer the horizontal alignment of the holder, when I use the iPhone as a navigation system. I believe in the vertical position could be found on rough road, the clamping force may not be quite enough. It was important for me to find a holder into which the Iphone also fits with a protective sleeve (SwitchEasy Vulcan). Direct hit. In addition to the very stable gooseneck holder Holder for the ventilation grille is not included. Both fit perfectly with me (Golf VI). Operation of Ihones is a bit shaky with the air vent holder. 5 stars I would have forgiven, though still a charge / audio cable fuerzs Iphone had been there for the price. That would be the perfect solution to use an iPhone as a navigation through the car speakers for me.
