Where is the ETC device generally installed?

The installation position of the ETC device for small cars is generally in the upper middle part of the front windshield, while for large vehicles such as trucks and buses, it is installed in the middle to lower part. The suitable installation position should be no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with anti-explosion film or those that have it installed later, which may affect the signal transmission of the microwave communication link, it should be installed in the microwave sunroof strip. ETC is the abbreviation for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, the vehicle owner needs to provide original and photocopies of their valid ID card and vehicle registration certificate. If the application is not made by the owner themselves, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. A bank card for deducting highway tolls is also needed, and the vehicle must be registered under the name of an individual aged between 18 and 60. Below are the precautions for installing ETC: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have windshields with a large rearward tilt angle, which can reduce the driver's field of vision. If this is not considered during ETC installation, it may increase the driver's blind spots. Installing it behind the rearview mirror on the right side can help avoid obstructing the view. Do not affect charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement because it has a solar panel on the back that can charge itself. Therefore, during installation, avoid the black areas on the windshield and positions that may block the solar panel. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-removal lever connected to a switch. After the electronic tag is installed, the windshield will press the anti-removal lever in. If the tag is removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. In such cases, you will need to visit an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing one device. When using ETC, note the following: The ETC transaction sensing range is 8 meters. To prevent issues with the ETC device of the vehicle in front, maintain a distance of more than 10 meters to avoid automatic toll payment for the vehicle ahead. The ETC lane recognition speed is 20 kilometers per hour; driving too fast may result in failure to read the vehicle device information and thus failed toll deduction. When using a debit card linked to ETC, insufficient balance may also cause toll deduction failure.

I previously researched the placement of ETC devices, which are typically installed in the upper central area of the car's windshield, near the rearview mirror. The advantage of this position is that the antenna directly faces the scanner at the toll station, ensuring the best signal reception. If you install it too low or too far to the side, such as next to the driver's seat, it may miss the signal and fail to scan the card at the toll booth. Also, be careful not to cover it with thick film, as this could worsen performance in cold winter temperatures or rainy weather. Some people extend the cable to the cigarette lighter for easy charging, but the position must be securely fixed to prevent battery disconnection on bumpy roads. In short, choosing the right location can extend the ETC's lifespan and make driving more worry-free. During installation, it's best to refer to the manual to ensure the correct angle and height, avoiding frequent repairs.

When driving long distances, I always place my ETC device at the top center of the windshield so I can easily glance up to check if the indicator light is on. An improper position can cause issues like signal blockage or scanning delays, leading to wasted time and unnecessary charges. Also, avoid moving the installation point randomly—there's usually a dedicated slot near the rearview mirror designed for it. Placing it correctly won’t obstruct your view or cause glare in strong sunlight. Once, I tried placing it on the passenger side, and the toll booth couldn’t read it, forcing me to wait ten minutes to readjust—a real hassle for daily commutes. Installation height is crucial too: too high and it might touch the headliner, too low and reflections could distract you while driving. Before sticking it on yourself, remember to clean the glass to avoid air bubbles. If you frequently switch cars, a detachable mount is a more convenient and cost-effective solution. These are just small tips to help others avoid common pitfalls.

I just bought a car and installed an ETC. The technician taught me to stick it at the top center of the windshield, right above the rearview mirror. Placing it incorrectly can cause trouble, such as scanning failures or higher toll fees. Proper installation ensures the antenna angle is aligned, with strong signals and fewer misreads. If the position is too off, it might also affect the battery, causing it to wear out prematurely. Adjust the height properly during installation to avoid touching the top. Stick it firmly to prevent it from falling off.
