Can ETC be installed without sticking to the windshield?

ETC can be used without being stuck to the windshield. Installing the ETC on the upper part of the windshield is intended to minimize obstruction of the driver's view while ensuring better recognition by highway toll station equipment. If you prefer not to install it on the windshield, it should be placed in an open area where it can still be seen through the windshield. For small cars, the ETC is generally installed on the upper middle part of the front windshield, while for large vehicles like trucks and buses, it is installed on the lower middle part. The suitable installation position should be at a height of no less than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 to 90 degrees. If the vehicle has a built-in or aftermarket anti-explosion film, which may interfere with microwave signal transmission, the ETC should be installed in the microwave window area. Here are some precautions for installing ETC: Do not obstruct the driver's view; the best position is behind the rearview mirror: Many car models have windshields with a steep angle, which can reduce the driver's field of vision. Installing the ETC without considering this may increase blind spots. Placing it behind the rearview mirror on the right side can help avoid blocking the view. Avoid interfering with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement, as it has a built-in solar panel for self-charging. Therefore, during installation, avoid the blackened areas on the windshield and positions that may block the solar panel. Do not remove it arbitrarily once installed: The adhesive pad has an anti-tamper pin connected to a switch. Once installed, the windshield presses this pin in. If the tag is removed, the pin pops out, triggering the switch and locking the device, rendering it unusable until unlocked at an ETC service center. This feature prevents multiple vehicles from sharing one device. Things to note when using ETC: The ETC transaction sensing range is 8 meters. To avoid issues caused by a malfunctioning ETC device in the vehicle ahead, maintain a distance of at least 10 meters to prevent automatic payment for the preceding vehicle. The ETC lane recognizes vehicles at a speed of 20 km/h; exceeding this speed may result in failed transactions. If using a debit card linked to ETC, insufficient balance may also cause transaction failures.

As a frequent driver, I also didn't want to stick the ETC directly on the windshield, worrying about affecting the appearance or leaving adhesive marks. I tried fixing it on the dashboard with a simple bracket and 3M tape, and it worked quite well. The key is to choose the right position without any metal objects blocking the signal, otherwise, it might not be recognized at toll stations. The ETC needs solar charging, so find a well-lit corner, such as the dashboard area below the windshield. I recommend buying a dedicated mounting plate or Velcro tool and testing the signal strength in a safe section beforehand to ensure normal use. Improper installation can lead to failed passage, which would be a big hassle. Regularly check if the tape is secure, as vibrations can easily cause it to fall off. In short, it's fine not to stick it on the glass, but you need to balance signal reception and charging needs.

From a technical perspective, it is entirely feasible to install ETC devices without adhering them to the windshield. ETC operates via radio frequency signals, and while mounting on the glass provides the optimal antenna position, alternative locations inside the vehicle—such as the dashboard or rearview mirror bracket—can be chosen, with the key being to avoid metal interference that disrupts signal transmission. During installation, use non-adhesive fixtures like suction cups or clips, but ensure to test the antenna's orientation toward the toll booth. Solar charging must also be considered; place the device near the glass rather than in a fully shaded area. Weak signals may cause passage issues, so it's advisable to enter toll booth lanes slowly to facilitate system recognition. In practice, many have successfully installed ETC units on sun visors or air vent slots without damaging windows. Regular maintenance to check adhesive tightness and prevent detachment is crucial. In summary, with proper positioning, non-glass installation is equally viable and safe.

As a privacy-conscious car owner, I dislike sticking my ETC device on the windshield for fear of exposing device information. I've found a simple alternative: securing it to the dashboard or door-side storage compartment with strong adhesive tape. Choose a location without obstructions to ensure normal signal reception. The ETC solar panel requires indirect sunlight, so avoid dark corners to prevent insufficient charging. During testing, I passed through toll stations several times, slowing down slightly to ensure stable signal transmission. This method protects privacy without compromising functionality – practical and reassuring.

For DIY enthusiasts, installing ETC without sticking to the windshield is a piece of cake! I use magnets or plastic clips to secure it on top of the dashboard, paired with strong double-sided tape, positioning it towards the sunny side to avoid signal blockage. Before installation, measure the distance to the antenna area and test toll gate passage to prevent misreading. Pay attention to solar charging—avoid placing it in complete shade. After modification, it's very stable, low-cost, and flexible. I recommend trying similar creative installations instead of sticking to traditional methods.
