Hi Guys, Has anybody on this forum installed, or ever dabbled with a car PC? I've got most of the gear ready to go in, just missing the screen and a few cables. The only bit that's got me stuck is working out how I can keep the Volume control functionality on my steering wheel. I imagine this is the case, but can anybody confirm that the wiring going into the original COMAND unit on my W208 CLK is CAN-Bus? If this is the case, I think I'll have to get a 'stalk adaptor' for an Alpine/Sony/Whatever which could convert the signal to resistive. Then I can buy a gizmo from these guys which will convert it into a USB input device.
