I am trying to determine if I have a Bose head unit or not. I

Looking at Crutchfield for aftermarket units and they need to know what's in there now. The radio in the ML looks like a plain Jane modular head unit no Bose labels on it. The front passenger speaker grill seats Bose but none of the others do.

Vin is 4JGAB57E34A464473.

any assistance is appreciated
