Aside from the fiber-optic connections, there are only 3 wires.

pin1-brown
pin2-red/yellow stripe
pin3-gray/black stripe

Does anyone have any information about this unit? Seems like all functionality is via the fiber-optic link. I assume the wires are there for B+, IGN + and GND.*

If I am correct, then are the steering wheel buttons for the VOL+/VOL- and cell phone SEND/END linked to this comand via fiber optics?

The wires are Ground (31), Permanent power (30) and MOST wake-up.

The volume control stuff etc. actually goes via the relevant CAN-bus but those are for the AGW that contains the audio amplifier too. Control between the AGW and the COMAND head unit goes via the fibre link.

Thanks, this makes more sense. I read more about the Audio Gate Way and the MOST network.
