c-map mapping software

[Twill23]

I was wondering if anyone has any experience with the cmap mapping software. I know that it is primarily used for ocean chart plotting, but they do make a chip for the great lakes region. I have a raymarine 760p(I believe that's the model) and a si-tex prism10nt that take this mapping software. Any insight would be helpful. I also understand that both of these unit are quite old.

I have the c-map maxx wide card for the great lakes. So far I don't see any problems with it. The maps are quite clear and do have some nice features. Depth contours seem to be on according to my fishfinder. I posted a couple screen shots of it under Standard Horizon CP180 review thread.
