optical disconnected while driving? That would suck.
I think the pac unit tricks the w200 into thinking that you have parked the car and performed the necessary steps to access all menus. With that installed, the optical should work, as well as access to the H701.
12 ft should be fine, but it will be close.
you dont' need rca's, run the ai-net to the h701, that will handle analog audio along with input selection, balance, fade, volume, etc from the headunit.
Life's too short not to be M-Powered
