>>On the panel for the rear view mirror <<

What do you mean by "on the panel"? If you mean the glass, that little circle is for a light sensor that helps adjust the auto dimming mirror.

No this is right on the plastic part that holds the mirror. It swivels from left to right and is vented. Thanks
