Review on 322 Anti-Glare GPS Visor/Shade by Dave Rasic

I use it on my Garmin 660 on my Harley. It's well attached. It covered the power button and part of the GPS antenna a bit, but not enough to cause any problems with them. It works most of the time, but like any screen, it's still hard to see when the sun is shining on the screen. like when the sun is behind me. It still works well in most conditions.
