I'm looking to purchase an LX470 with the night vision feature. I don't have any use for the night vision feature, but one thing that's concerning for me is that the windshield has a small square on it, where the night vision displays at. Is that small square a film that can be removed or is it built into the windshield? Reason I ask is because I tint all of my windshields with 15% tint and I don't know what the end result is going to be with the night vision piece on the windshield... In other words, if it's a film that cannot be removed, will the new window tint that I install have air pockets around the perimeter of the night vision square or does it go on seamlessly? Also, has anybody ever replaced their windshield that had the night vision option on it with a windshield without that option?
