So just an update. I had tried putting my tolltag in the black area but it was never recognized. I moved it to the upper left hand corner of my windshield, which is where I had it in my previous car, and lo and behold, it is working and being picked up by every toll gate I have gone through. Haven't tried it at DFW or Love Field, but it's working for now. Seems to be a lot of inconsistency as to what works for people but mine never worked in the black area to the right of the camera but is working now in the top left hand corner.
