The instructions for mounting this bit of mandatory payment for bridge and highway tolls put it at or near the center top of the windshield. I'm not an engineer but if I am correct, this will not affect any of the electronics in this area. Someone please let me know if I am in error. Personally, I would rather mount it at the BOTTOM center of the windshield.

I put mine at the middle top of the windshield. I can’t see it when driving as the rear view mirror blocks it from being seen .

I don’t know if it would be OK to put it in another location. But putting it in the recommended location is not visible or otherwise inconvenient for me.

I’ve been using it for 3 years now, and there has been no indication of it interfering with the car’s electrical functions.
