How to mount A30 EXPRESS transponder

Instructions for proper installation and a mounting template are provided with your transponder. It is important that these instructions are followed in order to ensure the transponder is properly read by the antenna/receiver at the toll plaza. If you do not have your A30 EXPRESS transponder mounting instructions, please review the following:

  • Step 1: Using an alcohol pad, clean the area of the windshield where the StraitPASS transponder will be mounted. If you do not have an alcohol pad, standard rubbing alcohol and a cotton pad may be used.
  • Step 2: Peel off the paper from the back of the velcro tab on your transponder.
  • Step 3: Position your transponder on the inside of the windshield, behind the rearview mirror. It is best to mount your transponder in the center of the windshield where the mirror hides it from view. The transponder must be mounted at least one inch from the edge of the windshield and two inches from the antenna of a remote car starter. For commercial vehicles with split windshields, place your transponder to the right of the split at the bottom of your windshield, to the right of the split.
  • Step 4: Press your transponder firmly against the glass.

For sticker transponders: To install, peel backing off of the sticker and affix directly to the interior of your vehicle’s windshield. Recommended placement is in the area behind the rear view mirror, a minimum of 5cm from any metal objects.
