Hello , Is there a way to stop or reduce the glare on the radio screen on sunny days. Driving straight into the sun is fine but with the sun to either side the screen glare is really bad. Tried with the instrument light turned all the way up but the glare is still bad. Any anti glare film that works. Thanks

 

3M Anti-Glare products are used in the aircraft industry to keep down glare on touchscreen displays, here's a link to their consumer site.

A film kit for a large Smartphone would probably give you enough Anti-Glare film to do a couple of radio displays. You just trim it to size with a razor blade.
