RE: 11x Question
Hothead is correct. It is the lexan plastic screen cover. I used a drop of c/a on the left hand corner to keep it in place. The plastic hazed a bit I the corner but it dosen't block the screen. It seems as if the fit of the screen cover isn't contoured correctly to the transmitter face. The double stick tape they use to adhere the cover is paper thin and dosen't hold. As to the glare on the screen with sunglasses, I ordered a screen protector for the 11x. Well see how that works.
