First, you need to remove the rectangular panel with the high-frequency speakers located opposite the rear view mirror in the passenger compartment. The panel's on the clips. Beneath the panel is a 3-side mirror on which the mirror is held. The panel needs to be pulled from any side and pull it on itself and then twist the smores.
After they have been clogged and disconnected, the mirror can be removed. If you unwind the last self-morse, the mirror will have to be held from the outside, otherwise it may fall.
