ipod-Rabbit integration
I used the Brodit mounting system aka ProClip in the USA. The system consists of two pieces: a mount custom-fitted for your car, and a cradle customized for your device. The mount installs in 1 minute just by snapping it on to your dash, and it doesn't leave any permanent mark. The cradle attaches to the mount using two screws. The ipod can slide up and out of the cradle so I can easily take it with me when I park.
The ipod integrates with the car stereo using the Dice i-VW-R VW Adapter. A standard ipod connector plus into the ipod, and the wire runs through the back of the glove compartment to the Dice i-VW-R box tucked behind the stereo. The i-VW-R then connects to the stereo using the CD changer interface. It also includes a similarly wired aux. mini input in case my passenger has a non-ipod music player.
