Hello Folks - the gizmo that apparently contains the compass has fallen off the back of my interior rear view mirror (see the attached photo).

It seems like it ought to just fit over the cylindrical mount that fastens the mirror to the car but I'll be danged if I can find the right way to position it so that it fits properly.

The service manuals I have are hopeless about this... hoping that someone has some advice so that I can reglue or tape this into place.

Thank you.
