Toll Transponder Location On Rx330

Question 407 Transponder on Rx330

New owner of a 2004 RX330.

We have an electronic toll highway here in Toronto (407 ETR) that uses these transponders which you are supposed to mount on the windshield right behind the rear view mirror.

In the US there is the EZ-Pass which I assume is somewhat similar.

The transponder is basically a low-power radio (RFID) that is picked by sensors when you enter and exit the toll highway. If the signal is obstructed (for example if there's metal between the transponder and the sensor) the signal will not be picked up and you get nailed with an extra charge on top of the regular toll.

Besides the transponder being ugly, the RX 330 has at least 3 sensors on the windshield: raindrops, temperature, light - one of these is actually on the back of the rear view mirror. So mounting this thing behind the mirror might actually screw something up.

Bottom line is I really don't want to glue this thing to my front windshield. Wanted to know if other RX drivers had any luck successfully putting these things anywhere else.

So any suggestions?

Here in Illinois they offer a transponder that attaches to the front license plate. I'm not sure if this is an option in Canada.

On my 08 I mounted it to right of the rain sensor no problems with anything.

With today's car designs, this isn't uncommon. Look for the detailed instructions from or call the customer service dept of the transponder provider for alternative location placements. Here in California, the transponders can be anywhere in the front dash or windshield (up, down, right, left). I've even had mine in my center console cupholder and it works just fine. The range that the transponders are detected in is much bigger than than the initial instructions lead one to believe.
