I've got a "Via-T" (one of those automatic toll collection RFID[I-guess] devices which let you drive on toll roads without having to stop to collect tickets and pay the tolls in cash/card on the spot).

I'd installed it on the back (that is, the forward facing) side of the rear view mirror in my 2020 Octavia Scout, on the passenger side as low down on that side of the rear view mirror as I could place it. (There's a sensor on the forward facing side driver side of the rear view mirror, so I didn't stick it on the driver side).

On a small number of occasions the toll device has completely failed to read, and on a couple of other occasions it has read very late.

Where do you stick your toll collection devices on your Octavias? Has anyone else encountered a problem with (I don't know, maybe something embedded in/ decaled onto the windshield just in front of the rear view mirror) interference with a toll collection device, either when stuck to the rear view mirror like I've done it, or elsewhere?

thanks!

Normal advice is to stick it on the windscreen within the hatched area near the rear view mirror.

 

Heated windscreens or heat reflective coatings can cause issues with tags I believe

On dotted area, as written in the manual.

 

Thanks @nidza. That seems to ring a bell, but I've just re-read the manual that I have ("OWNER'S MANUAL Vehicle and Infotainment SKODA OCTAVIA", manual barcode number appearing in the bottom right corner of the 2nd and 3rd pages "5E0012720AR"), searching for "dotted", "rearview", "rear view", "toll", and some other words, and I don't see anything about it.

Could you please post a screen shot or excerpt of that part of the manual that you have? Many thanks!

@JayLibove, sorry for a late response. It also bugged my head where have I seen a picture of dotted area with the tag attached, which I clearly remember - but it isn't in the car manual, it's within the tag installation instructions, please check mine (luckily there is an English version):

Thanks very much @nidza!

Really curious - those instructions show the toll device being placed ON the dotted-block stuff on the windshield (which I think are there to reduce glare in the driver's eyes when looking at the rearview mirror) and which I assume contain metal!

I didn't see in those instructions a dotted area on the windshield, just text describing what I'd already tried, and the picture which, per the above, surprises me.

When I drive along several hundred Km of toll highways in a few days, I'll test my toll device in my hand right in the middle of the windshield, to see if maybe I just got unlucky and it needs to be replaced.

Actually it is quite the opposite for majority of windshields: if they may contain metal, this is the area where it must certainly - IS NOT.  Dots are simply mechanical block of sunlight penetration, therefore the best place to place any RFID device.

 

Indeed, thanks! Per the Wikipedia article on "frits", these dots are ceramic, not metal. 

Tested. Works fine.

So, attached to the rear of the rearview mirror: bad; pegged on the windscreen just at the far edge of the black dots (just visible to the driver past the rearview mirror): good!

Thanks!
