A couple of other installation comments I could have made in the first post.
The window tint film is applied inside - experts on the web said its no problem applying suction cup mounts on the tint-film. So far I have had no problem.
last note: The yellow colored Logitech suction lever is too hard to turn to its latched position if you start with suction cup pressed hard to glass. I had to turn the lever 1/2 way before applying the suction cup to the glass to make the lever more operable.
