Consider a BLACK dash-mat with D.I.Y. aluminium foil on the underside. Between the foil and dash have fabric to ensure no direct contact between foil and dash and create an air space.
A) it reduces reflection in the glass
B) the foil insulates sun heat from radiating into the dash rubber
c) it reduces the polymer fallout to the glass
The oe dash on my previous car was 100% after 17 years of Australian sun with this mod.
(You may need to experiment with a hole in the foil if it shields your satnav sensor)
