The Volkswagen SHARAN CD Slot Phone Mount utilizes the existing CD slot to insert the mount, ensuring it does not interfere with screen or button operations. It includes a reserved spot for attaching a magnetic ring, which you need to purchase separately (58mm in diameter). You will also need to provide your own magsafe magnetic ring for the back of your phone or phone case. The mount now comes in two additional thickness models: 3.5mm and 4.0mm.
