My Response had the mirror bracket mounted on the center piece of the windshield. I liked that location a lot! Combined with the PTM 140, the mirror placement was perfect.
On the 200 the bracket sits on the driver’s side part of the windshield. It’s not ideal, as you always see parts of your own head in the mirror and for taller drivers it’s even worse. (That’s probably the reason why PTM sells these extensions that you see in @jayski ’s picture.)
I cannot move the mirror to the center piece, because of the thickness of the bracket, I could not open the windshield safely this way because the bracket would be the contact point when the walk through window is opened.
