    I've searched through a ton of threads on this, but I can't find consensus. I called both Sunpass (Florida) and E-ZPass (NY), who both said I needed a front plate mounted transponder. That would be fine, if it weren't for the fact that I don't have a front plate and have removed the bracket.

    Suggestions on where to put a front-license plate transponder when you don't have a front plate? A solution that involves velcro would be great, as I could then swap the two transponders when I was in CT vs. FL. Thanks.

    My MS60 hasn't been delivered yet, but my conversations with my DS and with the SunPass folks suggest that the only solutions for the new design are:
    1. Use a permanent SunPass sticker RFID transponder (which is, by far, the most common version now) and block with a steel plate that SunPass provides if you're somewhere like the I-95 Express Lanes (which are exempt from tolls for EVs).

    2. Use a suction-cup SunPass (which you can still find at Publix or buy online) and use the special baggie they provide to "hide" it from the SunPass system on exempt roads.

    You'll get the steel plate or the baggie when you register your EV with South Florida Commuter Services, which you can't do until after you've gone in person to a DMV office to get your HOV/Low-Emission sticker.

    In either case, the nosecone/front plate work-arounds aren't needed anymore because the redesigned front windshield doesn't block RFID. So if you prefer the "regular" SunPasses, you're in luck with the new model. If you wanted to completely hide it, you're out of luck.

    Because there are so few of us (relative to all other cars), I still find that the folks at SunPass don't give 100 percent consistent answers on this, and even the guidance from Tesla employees seems to be a little shaky. Make sure you're monitoring your SunPass use through their website until you feel comfortable that it's correctly logging your tolls.

    Super helpful, thanks. What was new to me is that "the redesigned windshield won't block RFID." Where did you hear that? If that's the case, I'm fine, I'll use suction cups and swap between Sunpass and E-ZPass as i need to....

    I had a 2013 P85 with the plate transponder hidden under the nose one. On my new P100D I have been using a suction cup mounted version directly under the camera/radar box behind the rear view mirror. It works just fine there.

    I use NJ Easy Pass from inside the windshield (December 2016 refresh MS) and it works fine. I keep it in the glove box and place it on the dash only when passing through the toll station (I don't use toll roads frequently).

    My facelifted MS AP2 has the EZ pass right below the cameras and works 100% of the time.

    I registered my car on sunpass.com with a transponder that I keep in a seperate car, and my tolls are removed via toll by plate. No problems so far.

    I have a 2016 Model S. I live in NY. I have an internally mounted NY EZ-Pass. It works 100% of the time. Here's how: Mount the EZ-Pass HORIZONTALLY but UPSIDE DOWN, tight against the rear view mirror housing about and inch down from the top of the glass.

    The reason for this is the black area next to your rear view mirror will allow the signals to pass through the windshield HOWEVER the transponder is on the right side of the EZ-Pass. If you mount the EZ-Pass right side up, the transponder falls outside of this black section. Hence, you must mount it upside down. The reason for mounting it horizontally, NOT vertically is that the receiver expects the signal to be oriented in a certain way and putting it vertically screws that up (or so I've read).

    That is exactly how my EZ=Pass is mounted. No problems in PA, DE, or MD.

    My understanding is that the MS manufactured before fall 2016 required this kind of acrobatics... there was a smallish rectangle of windshield that was "clear" for RFID signals. But the folks at my Tesla shop said it will now work anywhere on windshield. Again, I can't personally vouch for this, but I really grilled them about it because my community is gated and doesn't offer an alternative to RFID tags. They assured me that it would work anywhere it would work on any other car (i.e. any clear part of the windshield).

    I'll try to remember to report back when my car is delivered next month.

    Interesting, but I don't actually have a black area on my windshield. It's entirely clear, even near the cameras. AP2 thing maybe?
