Keep your phone in a holder when on the road and you will always have it within easy sight and reach. The fixed holder is to be connected inside the dashboard, this gives a discreet, neat installation without cables hanging over the interior! The adjustable holder fits for devices with and without skin with the following dimensions: Width: 75-89 mm, Thickness: 12-16 mm. Adjustable holders come in various sizes. Measure your device and compare with the holder specifications in order to make sure you have chosen the correct product (if you are using a skin: measure the device with the skin in place).http://www.baowei-china.com/fixed-holder/
