Review on LFOTPP Car Navigation Screen Protector for GMC Sierra 2016-2021 – Tempered Glass, 8 Inch IntelliLink, 9H Hardness by Scott Goff

The glass seems to be holding up well. Installation was cheap. They give you a duster, alcohol wipes (bone dry) and a "dust sticker" to clean the car window before installation. DON'T SPEND YOUR TIME on junky accessories. Just take a soft cloth and a bottle of Windex and give the screen a good wipe. Remove the plastic protective film from the glass panel (pull the small tab), then use the suction cup to attach the protective film and press to stick. Protective glass in relation to the outer edge of the touch screen. It's okay, I promise. I would recommend this protector with your own Windex as a cleaner.
