The special coating on the windshield seems to create problems for some RF or RFID devices. There is a non-coated clear spot on the windshield just above the rear view mirror that allowed me to place my automatic gate opener so that it would work. It wouldn’t operate properly anywhere else on the windshield. I’m wondering whether SunPass (the Fl equivalent to EasyPass) will work on the FL Turnpike). Haven’t tried it yet.
