Treading the USB cable trough the back of the center console. It was easier than I'd thought and the cable just ran itself into the upper part to be fished out.

The adaptor for the new unit. Besides power and speaker cables it also features signal cables for a remote, mute, hand brake and rear gear for different functions on the unit.
Thats it for now, to be continued...
