2011 Mazda2 Inside Mirror question

[BLAlley]

Does anyone know how to tighten or remove the inside mirror on a 2011 2? There is no set screw, only an iddly shaped notch that doesn't seem to lead anywhere useful.

I figured it out.

I figured it out.

Thanks for the update, would it be possible to post about how you figured it out for people seeking the same information. That would be very much appreciated, thanks again!
