Can I install the ETC device by myself?

ETC devices can be installed by yourself as long as you follow the correct installation steps. Generally, ETC can be installed in an open area on the front windshield, as long as it does not obstruct the driver's view. The optimal installation position is at the upper part of the front windshield, behind the rearview mirror, preferably around the black dot area. Installing it in the black dot area is mainly to prevent insufficient sunlight in winter, which may lead to low battery levels, as the black dot area can block some sunlight. ETC is an Electronic Toll Collection system used for automatic toll collection on highways or bridges. It works through dedicated short-range communication between the vehicle's electronic tag installed on the windshield and the microwave antenna in the ETC lane at the toll station. By utilizing computer networking technology and bank backend settlement processing, it enables vehicles to pass through highway or bridge toll stations without stopping to pay the tolls.
Last time I saw someone get stuck at the toll gate while trying to install their own ETC device at the highway entrance—it was quite awkward. Actually, I don't recommend DIY installation because the device requires professional activation, and the placement is also very particular. You need to avoid the black dotted area on the windshield; otherwise, the signal will be intermittent. Cheap devices bought online often get blacklisted by the system—it’s better to get one for free from a bank. My colleague tried sticking it on himself, but the solar charging spot was blocked by the rearview mirror, and the device ran out of power in less than a week. What’s even more troublesome is repairs—if a self-installed device has issues, you have to visit the service center yourself, whereas bank-issued devices can be serviced with just a phone call for on-site support.
