Can I apply window film after installing ETC?
2 Answers
You can apply window film after installing ETC. Since ETC devices are usually installed on the front windshield, and the film applied to the front windshield has good light transmittance, it won't affect the ETC device. However, dark-colored films may impact the solar panel of the ETC device. If you've installed ETC, you can first remove the device, apply the film, and then reactivate and reinstall the ETC at the bank. The ETC application process: Prepare the vehicle owner's ID card, credit card holder's ID card, credit card, and vehicle registration certificate. Visit the nearest bank branch to submit the application request and wait for processing. The function of ETC is to enable vehicles to pay highway or bridge tolls without stopping at toll stations.
I also struggled with the window tint issue before installing my ETC device, which mounts on the front windshield. Metalized films are absolutely not an option - they completely block ETC signals, causing failure at every toll gate. Ceramic or dyed films can work, but it's best to leave a palm-sized clear area around the device. I had the installer cut out a square section where the ETC goes. Remember to avoid the black ceramic dot matrix area behind the rearview mirror - that's the vehicle's signal concentration zone. If tinting after ETC installation, you must remove the device first to prevent glass scratches during cutting. However, removal triggers the anti-tamper lock, requiring device reactivation, which is somewhat troublesome.
