I have had several "Toll Unpaid" signals with PANYNJ EZ-Pass, and my monthly ledger shows delayed account reimbursements that appear to be related to license plate scanning rather than showing my transponder number. I found few posts here about the Subject issue, but this one,


has the advice

1) Passenger side
2) Just outboard of the dustpan
3) Just below where the glass transitions from shaded to clear

However, the attached photo shows that I (accidentally) followed exactly this advice. I concede that I'm actually touching the shading border, but I placed the transponder so that I could not see it behind the rearview mirror, a possible item 4 on the quoted list. This photo is posted upright, so the transponder is vertical (Edit: the lettering reads like the spine of a book-the photo below shows exactly what you see live, seated in the front passenger seat), as opposed to the way I had it in my previous cars, which didn't have the big "dustpan" installation.

Does anyone have additional data on this issue? Thanks.

Not to change the subject, the Port Authority of NJ & NJ uses NY State's "list" of high-mileage vehicles, and NY State still has not certified Bolts later than 2019. That means that I no longer get the (substantial) discount for a "Clean Pass" vehicle that I used to get with my 2015 Prius.

Here in WA we have a slightly different transponder, but I'm sure they operate the same way. I have mine placed to the left of the mirror, near the top of the windshield. It's hidden when the sun visor is used. It's never been an issue in close to a dozen cars I've had. I've only used it once in the Bolt, but since I haven't been notified of anything it must have worked.

Not sure what you mean by your 鈥渧ertical鈥 comment, but there are embossed arrows in either corner of the transponder that need to be pointing upward toward the headliner, as shown by @bartimusmaximus 鈥檚 picture.

That said, mine has had spotty pickup in MD ... on the JFK Mem Hwy, Ft. McHenry Tunnel, and recently on the (not so) Nice Bridge - where I actually pulled the thing down and presented it outside the window, and it still showed 鈥淚nvalid Tag鈥. Not sure what鈥檚 going on with it, but the billing seems to be right, with the plate number showing vs the transponder number, charging me the pay-by-plate rate

+1 on above- EZ Pass should be oriented in 鈥渓andscape鈥 mode not portrait. Also, some of the readers in MD are spotty. I go through the Harbor Tunnel frequently and every now and then I encounter the 鈥渋nvalid pass鈥 message but have not had any billing issues.

This is where I have it mounted in my 2022 Bolt EV. Been on the turnpike several times, checked my EZPass account, and it seems to be working fine.

I put a California transponder in a similar place, but at the top of the windshield and next to the cover behind the mirror. Worked fine getting read by the toll scanners, but the sticky Velcro eventually fell down, leaving the transponder on the floor. Then I just stuck it on the dashboard, which also works fine with the toll scanners.

I need to get one of those suction cup mounts for mine. I don鈥檛 want it attached to the windshield with the Velcro, and have been holding it up in my hand, but that鈥檚 getting old. I want to be able to take it off the window completely when not in use (which is the majority of the time).

Had the same issue as the OP. Our TXtag instruction say on commercial trucks it is acceptable to place it on the bottom of the windshield (center) just above the dahs board.
Our TX tag is however a much smaller device like a sticker approx. a size of a matchbox. LOL, millenials don't know what that is! :)

Side addition/correction, the PANYNJ has, automatically, resumed my Green Pass (EZ Pass) high efficiency vehicle discount. Since I had to "enroll" me second consecutive Prius twice, Certified mail, this is astounding good news. Bolt 2021 must have appeared on their list.
