Review on Universal Screen Protector Navigation Anti Glare by William Lara

I bought this for a Kenwood unit in my truck. Unfortunately, while this reduces glare, this screen protector makes it impossible for me to read what's on my screen. I changed the brightness settings on my device to see if that would help, but it made no difference. Totally useless - too opaque. I am disappointed that this does not work as advertised and will look elsewhere for a screen protector.
