I didn’t want to hang my NYS Thruway EZPass anywhere in the glass so I tried to hide it in a couple spots. First mounted it to the radiator support, but it would not scan at one of the toll stations. So during tire rotation time I pulled back the drivers side wheel liner, and zip tied the pass to the headlight bracket. This way the transponder is just behind the bumper skin, and ends up sitting fairly high. No issues so far.
