The choice for a freshly charged battery, a neat and comfortable installation. The holder is equipped with an Apple approved cig-plug cable for connection to the vehicle's 12 Volt socket. When you place the iPhone in the holder, it automatically connects to the charging unit. If you have a car with USB interface, you can disconnect the cig-plug from the holder's cable in order to get a USB-cable to connect directly to the USB connector in your vehicle. The holder is mounted onto a tilt swivel so you can adjust the angle and switch between portrait and landscape mode. Important note! In order to be able to transmit audio files from your device through the USB-cable this feature must be supported by the stereo in your car. This is easily tested by connecting your device to the stereo with the USB/charging cable that comes with your device. Charging through USB works regardless. Tablets should not be installed onto a car's dashboard if they block the view or block key controls. The ProClip is designed for installation of smaller devices (phones), not large devices (tablets). If you want to place a tablet onto the car's dashboard, each combination of tablet-car must be examined in detail by you in order to determine if such an installation is possible in the specific case. Consideration should be given to the position and how firmly the ProClip is in place, as well as the size of the tablet you wish to use. Brodit will not give any recommendations for such installations. An installation of a tablet onto a vehicle's dashboard is always done on the customer's own responsibility. Brodit recommends to use tablets on the car's headrest, installed onto a Brodit headrest mount.
