Can the ETC be placed at the black dot position?

It is acceptable to place the ETC at the black dot position. The installation method for the ETC is as follows: 1. Peel off the double-sided adhesive plastic film on the back of the ETC device and stick it to the upper part of the windshield, behind the rearview mirror; 2. Press firmly for about 10 seconds after sticking it on; 3. Insert the card into the ETC device and then pull it out, repeating this several times to complete the setup. The removal method for the ETC is as follows: 1. Use a hairdryer to heat the contact surface between the ETC device and the glass to soften the adhesive, then gently remove it; 2. Soak a towel in hot water to heat the adhesive tape on the back of the device; 3. Use a scraper to remove the adhesive tape and take it off.
When dealing with this type of issue, I've found that ETC devices should not be placed on the black dotted areas of the windshield. These dots are typically metal-coated zones that can easily interfere with signal transmission, causing the toll system to fail to read the card. The correct installation position is the central area at the top of the windshield, where it's more open and ensures stable signal reception. If accidentally installed near the dotted area, signal instability or toll collection failure may occur. Sometimes, I encounter car owners complaining about delayed toll deductions precisely because the device is positioned too far off-center. To ensure accuracy, the glass surface must be cleaned before installation, the device should be firmly attached using the provided adhesive sticker, and any metal films blocking the signal should be checked. These small details can save a lot of trouble later. I always advise car owners to test the device at a few toll gates after installation to confirm it's working properly before hitting the highway, avoiding sudden braking accidents. In fact, many repair shops offer free inspection services—consulting them when possible can help avoid potential issues.
