How you fix the bracket to a MS 1260. It looks like it comes with a bracket that fits in the hole behind the shield. Also there is a quick release mechanism on other mounts that don't appear to be present on this mount?
I fitted eco tech sat nav, remove shield with 3 bolts, insert little square in recess the bolt on main arm and put screen back on. I would use some washers though as eco tech on mine came loose without. If you don’t have little square bit u having a missing part I would say if phone mount same.
