I had trouble with reflections on the screen of my GPS. The light body-colour of my Quest gave a disturbing reflection.
My wife advised me to iron some black material on the body. The same material she uses as a lining for the clothes she sews. It’s called “vlies” in Dutch.
So I took some of that material and glued it with a flat-iron on the innerside of the Quest.
Within a few days I’ll visit the Easter-meeting for recumbentriders, so during the 250 km ride it would be nice if the GPS works without any problem 😉
