The buttons for mirrors with features like OnStar are usually housed below the glass portion of the factory rearview mirror. Because they are lower than the glass portion, it is possible that adding the K Source mirror, # KSRM011, can be completed without blocking the buttons on the factory mirror.

You will need to measure to determine if the buttons will be blocked if adding this mirror. The overall height of the mirror is 3-3/8 inches. Find the very center of your factory mirror (not the center of the glass but the center of the whole mirror including the housing) and measure down 1-3/16 inches. From that point measure to the left or right 9 inches (in the direction of the buttons).

This is the approximate area the bottom edge of the mirror will be once installed. When measuring, if you find the buttons will not be obstructed, it will fit.

Another way to determine fit is to cut out a piece of paper or card board that is a 3-3/8 x 18 inch rectangle. Center the cut out piece on the factory mirror to get a good approximation of where the mirror will be relative to the factory mirror.
