Haven't come across any issues with the reflecting sun yet, but my only (small) issue I've had is when I have my brights on at night. The blue light reflects off the chrome brace on the windshield and is very bright.
I like to have my dash as dark as possible so as not to affect my night vision.
Was thinking some black tape on the brace but that'd ruin the look. Now thinking a small circle of window tint on the speedo just over the light, to dim it a little further.
