Transponder Mounting Instructions

When to Mount the Transponder

Transponders should be mounted when temperatures inside the car are 50-85 degrees Fahrenheit.

Where to Place the Transponder

The transponder goes on the inside of the windshield close to the rearview mirror. Place the transponder as high and as central on the windshield as possible. Tip: Place the transponder slightly to the right of the rearview mirror so it is not in the driver’s field of vision.

Make sure the transponder is at least three inches away from any metal, tint, antennae or defroster. Also, avoid the black dots that may surround the rearview mirror. They can keep the transponder from being read accurately.
