Nav protector works fine for me....I did have to buy a few of them to get it applied correctly....and they aren't cheap. I do have a few air pockets near the bottom, but I'm ok with them. They can custom size them for you at no extra charge. I just looked for the measurements I sent them, but can't find them. Feel free to have them reference my order (Byron Ricketts /

You have to be very careful when applying the proector....barely touch the edges and use a credit card to ease the protector into place.
