There are 4 buttons on the rear view mirror. 1 of them is to turn the auto dimming off and on. Then there is one button for OnStar and an emergency button. What is the last button for. It just has a dot on it and when you press it,it asks for a command. I would like to know what this button does.

You can set it up so you can use a cell phone through onstar. You use that button to tell it the phone number you want to call.

What car do you have?P.S. Check your manual, it should have button descriptions in there.
