I've been using C-maps since 1997. Had EX10, used in 182 and 206 now have the IIIC for the last 2years.  I doesn't work very good on the yoke, its big, but the knee or the attachment between the seats will work well. We even use it in the citatation we fly because of the great color moving map. Its big. I have it mounted on a big clamp and it mounts between the pilots seats in my C-310. So you can see I use it between different airplanes. I really has every thing you need and more. They were talking about getting wsi able to read on it so we'll see at Sun-n-fun.
