Where to Install ETC?

[EstherAnn]

ETC is generally installed on the right side of the rearview mirror inside the car, on the windshield above the passenger seat. The installation requirements are as follows: 1. The height should be no less than 1.2 meters and no more than 2.5 meters; 2. The installation angle should be between 30 and 90 degrees; 3. For small vehicles such as cars and minivans, the OBU device should be installed in the upper middle part of the front windshield, while for large vehicles like trucks and buses, it should be installed in the lower middle part; 4. For vehicles with built-in or aftermarket explosion-proof film, since the film contains metal ions that may interfere with microwave communication signals, the ETC should be installed on the microwave sunroof strip or a rectangular area of 8 to 10 centimeters should be cut out of the explosion-proof film; 5. If the car windshield is too thick or has been modified, it may cause ETC signal transmission failure, and professional assistance from a repair shop should be sought.

After driving for so many years, the ETC device is usually installed on the upper part of the car's windshield, right below or next to the rearview mirror. This location is the standard recommendation in design because the toll station antennas can most effectively receive signals, ensuring quick passage. I've installed it myself multiple times—first, thoroughly clean the glass surface with an alcohol wipe, then peel off the double-sided tape on the back of the device and press it firmly into place. The whole process is simple, but the position must be carefully chosen to avoid blocking the front view or placing it too high for aesthetics or too low where it might interfere with instruments. After installation, power it on to activate; when the signal is stable, you can pass through toll stations almost without slowing down—it's really hassle-free. If the windshield has a metal film, it may weaken the signal, requiring adjustment of the position or moving to a film-free area. Beginners are better off going to an authorized shop for installation, where they use professional tools to test signal strength, avoiding future troubles, especially delays during high-speed driving.

ETC devices are commonly fixed at the top area of the windshield, just above the rearview mirror in my car. During installation, first clean the glass thoroughly, then press the attached adhesive tape for a few seconds to secure it, ensuring the device stands upright without tilting. Choosing this location ensures smooth radar detection without interfering with the driver's view or accidentally triggering the wipers. Sometimes poor signal may be due to loose adhesive or battery issues, so I regularly check the charging status. For long trips, it's important to test the device's functionality at toll stations in advance, as repositioning it can be troublesome if placed incorrectly. Don't worry about the device being too high and affecting aesthetics—manufacturers have considered concealment in their designs. Keeping the surface clean ensures stronger adhesion and minimizes installation errors.

Typically, the ETC device is affixed to the top of the car's windshield, and my family's car has it installed next to the rearview mirror. This position does not affect driving safety and ensures strong signal reception for smooth passage at toll stations. It can be securely installed with adhesive, but avoid placing it where the windshield wipers might block the signal. Choosing the correct position can save time.

Most ETC devices are installed in the upper area of the windshield, such as behind the rearview mirror. When installing it myself, I first clean off dust to ensure reliable adhesion, and the position shouldn't be too low to avoid instrument interference. Note that metal films may reduce signal strength, so try adjusting the position a few times. Activation is simple after correct installation, allowing quick passage through toll stations and eliminating the hassle of cash payments. If the signal is weak, check the adhesive strength or try reinstalling in a new location.

The ETC device is installed in the upper space of the windshield, and my car has it mounted around the rearview mirror. Choosing this location well ensures the antenna works efficiently. I researched the impact of positioning on signal transmission before installation, as tinted films or dust could potentially cause issues. After securing it firmly with double-sided tape, I turned it on for activation, and the system connected quickly. Here’s a small tip: avoid mounting it on the rear windshield or door frame positions, as unstable signals may cause delays at toll stations. Regularly wipe the device surface to maintain clarity, and there shouldn’t be major issues with long-term use. If installed incorrectly, simply reposition it promptly.
