What's that round button on the center of dash near windshield?

Photosensor for auto headlights? Something else?

The 'round thing' is also a photo sensor for the automatic climate control.
Notice there is one on the deck behind the rear seats too!

It may be for the "trunk monkey" option. Push it and if a monkey comes out of the trunk, you'll know.
