Hey Troop, it was actually neither morning nor afternoon when you posted, but just after midnight

Unfortunately, I can’t be a lot of help, for a couple of reasons. First, I have the forerunner of the 10c Evo, which was the 10c Pro, and it is slightly different in mounting and form. Second, I have used the permanent (screw) mounting plate and can’t find the old stick-on plate....if there was one. The mounting is definitely different from non camera Sena gear, as the 10c needs to rotate up/down to get the right angle for movies. If you put a normal Sena sticky mount on, the camera will be fixed, and may point at the sky or your front guard. I have included a photo of my mount, where you can see the rotation features on the mount and the camera. Hope this helps in some small way. There are a couple of decent u-tube reviews on installation where the mounting is mentioned.......Cruizeman’s Garage.
