glareshield idea
I'll vote for darker interior colour, as I hate all the reflections in the canopy!
( mine is beige = not good)
my dash was flat black, but it marks up pretty easily if you set things on it.
I bought a BBQ floor mat, ( $10) flipped it over, ( naugahyde pebbly side down) and trimmed it to fit the glareshield. a few tabs of 2-sided tape keeps it in place, along with the fuel hose and pipe insulation on the sharp edge.
The side exposed is a slightly fuzzy felt look, zero reflection, and ....bonus!....you can velcro anything to it!
I put velcro hook tabs on my SPOT and it sits nicely there....and would work for MRX, GPS etc....all the **** we put up there that probably should be secured!
Eventually the velcro pulls the fuzz up, so after a few years I'll want to replace it.
