Toll transponder placement - 2023 Prius

Mine is there and works fine

 

Mine is also there and does not have an issue.

 

I did not realize the transponder could be placed on those dots. I had planned to put the transponder on the dash, behind the entertainment screen where it doesn't block any of the view and can't be seen by driver or passenger. Still testing whether it works there, but I can't see why it would not. I guess if you can place on the black dots surrounding the mirror that may be as good, or better.

 

I used to put it on the front window. But as it turned out, it works fine just keeping it in the glove box in front of the passenger seat. No messing with adhesives.

 

Pennsylvania EZ-Pass transponders use suction cups instead of adhesives. I placed mine just below the frit behind the rear view mirror.

 

Those black dots are just "paint". They do not block RF.

 

I like that the best, if it works. Going to try it.

 

So if they are "paint" do they serve any functional purpose?

 

A slight sun screen. Mostly useless.

Wow, lots of good info about the black dots. Thanks for providing the link.

 

I couldn't get it to stick there so put it here:
