Anyone having trouble getting the RFID transponder to work when you drive through the toll collection points? I mounted the Fastrak transponder in the lower left corner of the windshield, but no beeps. I was wondering if anyone else has had luck with another location or knows of a "window" in the windshield coating that might allow better RF transmission. Seems many new cars have a coated windshield to reduce IR heating in the interior, but this can block RF signals.
There are also transponders available that mount on the front license plate instead of on the windshield. I've ordered one of those from TheTollRoads and assume that will work, but worried about aesthetics of a black box on the front of the car in addition to a front license plate bracket.
I guess in the mean time I'll just enjoy free tolls since I don't yet have my plates and the current transponder doesn't work :-)
