ZX1Cruiser: Haha, but your still have a lot more car-pc's than me. I'm behind on that (so far).
Right now they are just connected to the same car-pc for temporary.
I'm in the middle of the center-console fabrication (isn't the gear/handbrake box called center-console). This will have system #2 installed, so they will run at each their own system.
Right now I can't even show different sources, as the specific boards doesn't supports extended desktop mode...
