Looking for measurments on the nav control opening.
 

I’m trying to figure out how big the opening is for the nav controls that are right behind the sifter/gear selector. However, I need to know the opening size as opposed to the size the nav buttons take up. As near as I can tell (obviously, I don’t have a nav) there’s a bezel that wraps the buttons and “covers” the hole to provide a finished look. So what I am looking for is the opening measurements on the underside of the trim panel that covers the nav system. Any help would be appreciated.

TIA
