I have mine stuck to the plastic of the enclosure for the lane departure and forward collision camera. It blocks a bit of the upper right side of the video, but there's nothing really happening there that I ever need to see on camera, so I feel I still have a good view of the road ahead. I haven't had any issue with it not sticking in the 6 months it's been installed, but mine is very small and light.
