You don’t necessarily need to place the I-PASS transponder exactly above the rearview mirror. It can be placed anywhere in the center section of your windshield, behind the rearview mirror, to communicate with the toll plaza equipment. It can be placed closer to the mirror, lower or even to the side, as long as there's no metal blocking its signal. The key is to ensure its top side is facing up and front side is facing the windshield. The gray box near the mirror, often related to features like rain sensing wipers or light-sensing headlights, should not interfere with your I-PASS' functionality.
