GPS & EZ-Pass don't co-exist peacefully

I just drove back and forth between PA and MA. No problems with both either way. Turnpikes, Bridges, etc. all OK

Never had a problem and I use all the toll facilities in the New York City area. EZ-Pass and Nuvi 350 works for me.

phil nice AV. Were you at the game by any chance? we were in tier box 616 row A. what an amazing time.
now back on topic. ITs funny that I found this post, I just got a letter in the mail form ez pass saying that i have been running tolls and my ez pass account is getting pulled? The times on the letter exactly correspond with my nuvi 760 purchase which i use everyday to work in nyc. im really interested to see how ez pass will take my plea that its my garmin and not my omission of paying that is at fault. I never saw anything but green lights when i went thru?! interesting..
not blaming garmin just curious to see what is the real problem.

I have had no problems with GPS and ez-pass conflicting while using it in my semi. Just got a tag for my car and will test it out on a trip to central Wisconsin next week, hopefully it will continue to work flawlessly. Love my C330 otherwise known as Mot Mot.

my Ezpass didn't register on the toll on the Garden State Parkway in NJ. On my return trip, i turned off my GPSr and the Ezpass had no problem.

I drove the Garden State up and back to NY with both my Garmmin 660 and my EZ pass hooked up. Both worked fine the whole way.

on a trip to Vermont...no problems whatsoever.

I have not had a problem in 2 years of driving through tolls with any gps.

Hmmm, is your GPS one of the ones that receive traffic updates? If so, which updates do you get Navteq or MSN?

I haven't had any problem with mine, but then it doesn't get traffic.

Not sure if this has been mentioned yet...but what type of car windshield do you have? Some of the cars now have a special coating on the windshield which looks strange when wearing polarized sunglasses. I wonder if that can make it harder for signals to get through, such that having the GPS on makes it impossible for the ez pass to work anymore.

I get traffic and my EZ Pass/Garmin combo works fine. I drive a 2004 Outback. I have no idea if there's anything special about the windshield. I guess that means there probably isn't.

I have to guess its your car. I may be wrong but ezpass is rfid so i dont think this is possible.

No problems here with tomtom (on htc kaiser) and magellan (PND) and ezpass.

Nuvi 360 or 750 perform fine with EZ-Pass from Maine to New Jersey on a regular basis.

I have never had a problem with my EZ-Pass in the nearly two years that I have had my nuvi 200 mounted. However, my vehicle icon does do a 90-degree turn every time I go through the toll booth. It recovers its orientation in 5 seconds or so.

Passing through the booth shouldn't block the GPS signals long enough to do that, so I suspect some kind of interference from the EZ-Pass.

.

Never had a problem with EZ tag and Nuvi 360 both mounted to front windshield.

linked via Bluetooth to the 680, all play together nicely in our Odyssey. I don't think I've actually been ON the phone at the time of EZPass reading, but I might try that one day just for kicks.

oh, more details:
EZPass mounted per instructions behind rearview mirror.
680 with beanbag on dash.
Cell phone on tray between seats or stowed in cubby below radio.

I have experienced the "EZPass working when buried under seat phenomenon". This happened to me before I owned the GPS. In Maryland, when they ship you the interior EZPass unit, they send it to you in a shielded plastic pouch, with instructions to keep the pouch in your car, and place the unit in the pouch if you do not want the EZPass to be read.

Here's a theory, could the GPS have enough shielding internal to the unit (to help with FCC compliance) that it essentially blocked your EZPass signal? If the EZPass sensors are indeed directly overhead, it sounds like you inadvertently put your GPS(shield) in the exact right place.

You don't say what type of vehicle that you have. The link below is from the Illinois Tollway site and is a list of known cars with "difficult" windshields that interfere with tollway transponder signals. It's possible that your vehicle is one of the difficult ones and had a very weak (but usable) signal and adding your GPS provided just enough extra blockage to interfere.

I just used my Fast Lane and 650 in IL this past weekend and not problems here.

I've been using my Garmin 760 for a few trips along the Northeast I-95 Corridor without any problems.

I have GPSr, ez pass transponder, blue tooth, cell phone, sometimes walkie-talkie (no CB any more). All work for me very well.

Putting the EZPass in a microwave oven works good for blocking the signal. Just be careful the microwave oven doesn't go on by accident like mine did! What a smell!

Gee, that's more high-tech than Illinois. Here, they ship the I-Pass to you wrapped in tin foil.

Had simular problem. moved ezpass away from garmin. ok now.

My Nuvi 680 and my ez pass tag are within inches from each other and i have no prob. I also have a sirious radio inches away as well, and all is well, so far.

No problem for me either.

no problems here with ezpass and nuvi 765t. Hit NY thruway and Pa/NJ bridge

Some cars have restrictions where the device can be mounted. I would suggest that you contact the agency where you got the E-ZPass to see if there are any specific mounting directions for your make / model of car.

As the other posters in this thread commented, you see to be unique in having this problem. Perhaps you should consider a license plate mount E-ZPass.

never had a problem with mine either. hope its working better for you

I use both regularly in my car. The EZ Pass is 3 inches above the Nuvi & I have never had any problems.

Something else is happening.

...when using my TomTom One and EZ-Pass mounted on the windshield.

Since I use my EZPass in three different vehicles, I 'violate' the rules and place it on the dash in the space near where the defroster vents are. Sometimes when turning (most often on the very sharp turns at the toll plaza exits/entrances) the EZPass goes flying across the dash. Once I needed to pull over and search for it, since it slammed into the passenger window and disappeared under the seat! One other time, it slid to the corner of the windshield on the driver's side. I left it there, but it failed to read at the Indiana Toll Road. They have gates there, so people were pretty annoyed, especially the semi behind me that backed up to use another lane.

I pressed the help button and a lady came out with a barcode reader, I handed her the EZPass, and she read the barcode on the unit, and the gate opened.

In most states with these passes, you are required to register the vehicle license plate and description. It is my understanding (they do this in the Bay Area in CA) that they review the videos or photos of toll runners and update the billing records based on this info. I often carry my FasTrak (N CA) with me in rental cars and register the car when I get to the hotel. Then I unregister it when I get home (hoping nobody runs a toll with the rental car in the meantime!!!) On a recent trip from OH to the East Coast, several times the light at the toll plaza did not turn green, but I was billed for the toll according to my statement, so I presume that someone cross-referenced the license plate with the toll-running.

Also, both my FasTrak (N CA) and EZPass (PA) came in a silver antistatic-type pouch with the instructions to keep it in the pouch if you do not want it read... in CA, a carpool lane is free on the bridges, but if you have a FasTrak you will be charged anyway unless you put it in the pouch or elsewhere where they cannot be sensed.

Oh, and by the way, I don't think that I have ever had an issue with the EZPass and my 765T (or the FasTrak and my 680). That is unless these cases were examples. I had my Valentine V1 radar detector, the 765T, and the EZPass all within a couple of feet of one another for the entire time.

When I had my 350 on the windshield, it messed up the compass on the rearview mirror. So I'm not surprised there may be some interference issues.

I've since moved the nüvi to the center console, and I haven't had any problem since.

I've had no issues with my 765T and my FasTrak toll transponder being mounting right next to each other..

maybe something else was causing it

I don't think they update their billing records based on the video shots. What they DO is bill you automatically for the toll if your license plate is on file and the reader does not register. I really don't think it's necessary to notify them that you will be using a rental car for a couple of days while on business. I would be afraid that it would somehow remember that temporary assignment and bill you for someone else's tolls after you turned the rental car back in.

don't have an easy pass... but was watching my GPS to find out where i was and the problem was that the GPS drove my in an area where there was only EZpass lane That's an other type of problem but this one might be more coming from me.

No Problem with my 660 or 885T

No problems sometimes the nuvi360 sits in a bean bag about 1 1/2 feet away from each other.

No problem with my Nuvi 660 and I-pass. Have GPS directly under IPass on dash.

No problems with mine.

Nuvi 760 no problem in the Pennsylvania area!

I have had no trouble with my EZ-Pass just above my gpsr.

Works well for me, never had a problem....

never mind....

edited 3 times, i need to read all the posts before replying

By registering the car and plate on the rental, I assure that I don't get a bill from Hertz if the FasTrak unit does not work...

i've had my Garmin next to my ez-pass for the last 2 years and i have never had a problem either.

With two pages plus on this subject, there seem to be one thing missing. A lot of people are stating the GPS model and how far away it is mounted from the EZPass, But what we really need it the type of cars that are having trouble. This way we can see if there is a pattern or if this is a random problem which I doubt it is.

If your having this problem reply with the GPS model and make along with your car's make and model and also where you have both the EZPass and the GPSr mounted.

For confusion sake if your not having a problem, then no need to reply and clutter the thread. This seems to be the best way to figure this out

You can also look at the link below and see if your car is listed with a problematic windshield.

I did not have any problem. I always cross the NJ brige every day.
