A:AnswerIt did not come with any securing device. I did tie a string around the mount and ran to my door handle when i ised it, just incase. But it has held on perfectly to my street rod.
A:AnswerMost dashboards are not completely smooth, you would be better off attaching to the windshield, the attachments included would get you the right angle needed to catch the best view.
A:AnswerI own a Gopro Fusion, a 6 and an 8, it works on all of those, the MAX has a mount built in to the camera the same as the 8, which folds into the bottom of the camera. It's a standard mount for Gopro. You shouldn't have any problem.
A:AnswerYes, there is an attachment thing so if you have like a waterproof case on the camera itself you can attach it with the pin thing. So technically it should work for all as long as you have the right shell for the camera itself. Also works like that for body mount ones that use strap.
