Do I need to remove the ETC when applying front windshield film?
4 Answers
When applying film to the front windshield of a car, it is not necessary to remove the ETC device. You can simply cut out the area of the film covering the ETC position, as removing the ETC device will cause it to become invalid and require reactivation after reinstallation. How to activate ETC: Insert and remove the ETC card twice in succession until the electronic tag screen displays 'Bluetooth is on.' If inserting and removing twice without the electronic tag displays 'Tag invalid,' this is normal and does not affect activation. Alternatively, you can press the button on the top of the electronic tag to enable Bluetooth. Turn on your phone's Bluetooth, open the corresponding mobile app (usually a download QR code is provided on the electronic tag), and enter the device activation interface. Click 'Connect Device' and wait patiently for the 'Connection Successful' prompt. Once connected, upload a photo of the vehicle's front to complete the activation.
As an automotive enthusiast who frequently deals with vehicle customization, I can explain this from a technical perspective. ETC devices primarily rely on radio frequency signals to function. The tint film on the windshield, especially those containing metallic components, may block signal transmission, leading to reduced sensitivity. Therefore, the ETC device must be removed before applying the film. Otherwise, if the film covers the device's position, the signal will be interfered with, potentially causing the ETC to fail recognition at toll stations. I recommend removing the device during tinting, thoroughly cleaning the glass surface, and then reinstalling the ETC in an area unobstructed by the film after application, such as avoiding the tinted sections. This approach not only prevents additional disassembly risks but also ensures driving safety. Additionally, choosing appropriate non-metallic tint film brands can minimize signal issues. In summary, professional tinting procedures always include handling ETC details—don’t skip this step to avoid compromising toll passage efficiency, as the impact is too significant.
As a hands-on DIY enthusiast, I learned a tough lesson when applying front windshield film to my car last time - I overlooked the ETC issue. After installation, the ETC signal kept dropping, causing fines at toll gates before I realized metallic films interfere with the device. Now I always remove the ETC before filming, thoroughly clean the glass area with cleaner, and ensure bubble-free application. After filming, I reattach the ETC securely in a new spot away from the treated area for uninterrupted signal transmission. This simple 5-minute process saves major headaches. Next time, consult professionals for compatible non-metallic film brands and check the ETC battery to extend its lifespan. Remember - this small precaution significantly improves driving convenience. Don't lose big by neglecting small details.
I recommend removing the ETC device when applying a windshield film for a straightforward reason: the filming process can easily cover the ETC position, leading to signal blockage or device damage. I experienced this myself—without removal, the film didn't adhere evenly, and the ETC later loosened, requiring time to fix. The practical steps are to safely remove the ETC first, thoroughly clean the glass surface, then apply the film smoothly, and finally reinstall the ETC in a film-free area. Choosing a non-metallic film ensures better compatibility with ETC functionality, avoiding unnecessary interference. In short, simple preventive steps are key to protecting device efficiency, and film shops often remind you not to overlook this.
