TEXAS TOLL TAG PLACEMENT UPDATE

For toll scanner it doesn't matter since the entire car have to pass under it anyway.Arcooke- I'm in the RF business, so no, I don't see how the windshield would provide much gain. The sunroof doesn't work for me because for our garage entry the reader is in the front at a 45 degree angle, so it absolutely must be windshield mounted. The instructions are probably meant for cars where there are no such large adhesive bands, following the instruction will end up mount the tag way too low, which is why it wasn't getting picked up. This worked flawlessly, and now the tag is invisible from the outside as well, which is an added bonus. So I ended up putting at right at the top of the windshield on the inside, within the factory tint strip next to the rain sensor, which is about 3.5' down from the metal roof of the car from the outside. The top of our windshield inside and outside have a fairly large distance gap because of the black band of adhesive.

But if you have a sunroof, and the tag fits under the sunshade (the TxTag is super thin) I think it is a superior location to the windshield.Sorry I should've provided an update to this, but I ended up going against the directions on the tag that says you have to be 4' down from the top of the windshield. I think these toll companies instruct users to put the tag on the windshield because all cars have windshields, but not all cars have sunroofs. This will be my TxTag location for all future cars for me. You might want to keep it back from the frame a bit (~ 4 inches?). Mine is more towards the back side of the sunroof more than 4 inches from the frame, but I think it would work just as well towards the front edge. It is also not an issue if I ever need my windshield replaced. I have the inside of my windshield slightly tinted which would prohibit the TxTag from working inside the windshield. It reads just fine and is visibly out of the way. I don't have an ES, but I do use a TxTag here in Houston. Is there something special about the Lexus windshield that is not playing nicely with these RFID toll tags? Where have you guys placed yours? I also tried mounting it just to the right of the humidity sensor inside the tint line, about 2 inches away from the top, after seeing this post, and that didn't work either.but would be nice if that worked, because it will hide the tag from outside. At that location, it's definitely more than 4 inches away from the top of the windshield, but perhaps too far down. The 'right behind the mirror, 4 inches from top of the windshield' instruction doesn't work, because we have the black plastic box containing the cameras behind the mirror, so I had to go to the next closest spot, which is just under the humidity sensor. It appears even the toll lanes are not reading the tags, and are instead falling back to reading my plate to charge me. I know our garage equipment works, and it worked flawlessly on my previous car. The new Eztag I got is having a hard time getting picked up through the windshield of the ES.I even tried a Txtag (but didn't activate it) and it's also not getting picked up. My work garage uses the Transcore reader just like all the toll roads around here in Texas, Oklahoma, Kansas area, it basically reads the toll tag and opens the gate without us having to swipe badge to go in and out.
