Checked out the other threads on this. Discovered the reason for the small blacked out portion of the windshield on the passenger side of the rear view mirror as BOATERVA mentioned above - for placement of stuff like toll transponders. I don't use the EZ-Pass often, but I'll report back the next time I use it at that spot on the windshield. Other threads indicated that's THE spot to put it (problematic with mounting behind nosecone). It's either there or the panoramic roof since I tinted the back window as well.
