The mobile phone is simply clamped in the holding tray and then click them into the steering wheel holder. This holds as absolute, but Skepitker can stretch even a rubber across the phone, but the course is then in the viewing area. The mount system including mobile phone can be easily carried between ausklicken and plug. It should be noted that there is no possibility to leave Sleeves to the mobile phone. Weatherproof The iPhone is therefore not packed. But I am anyway Schönwetter driver and if necessary the phone comes in the jacket.
