This is not what you asked but this is the mount I will try out next week:

I have not used it yet, only tried fit and it will work as a windshield mount for my small Nikon camera (that takes video). The suction cup is very solid but I'll have to see how solid the camera is. I will need to invert the video - not sure how hard that is - but I'm going to give it a try. I will be driving the blue ridge parkway - a scenic route in North Carolina and Virginia - and want to be able to make videos as I drive.
