Where to place the OBU?

ETC's OBU is generally installed on the front windshield of the vehicle, as long as it does not obstruct the driver's view or interfere with ETC communication. OBU is the common name for the electronic tag used in the Electronic Toll Collection (ETC) system for highways. When passing through highways, vehicles equipped with an OBU can complete toll payments without stopping. Relevant information about ETC is as follows: 1. Introduction: ETC is an electronic toll collection system for automatic tolling on highways or bridges. 2. Working Principle: ETC operates through dedicated short-range communication between the vehicle-mounted ETC electronic tag and the ETC microwave antenna installed in the toll lane, utilizing computer networking technology to process backend settlements with banks, achieving the goal of vehicles passing through highway or bridge toll stations without stopping to pay tolls.

When someone asks me about where to place the OBU, I immediately think of the inner side of the windshield. The OBU is a small device, like an ETC tag, and it should be placed right above the windshield in front of the driver's seat, preferably near the rearview mirror. This position is crucial because it offers the clearest view without obstructing visibility, while also ensuring the antenna receives signals better to avoid issues at toll booths. I've tried it myself—if placed too far to the side or too low, the antenna signal gets disrupted, leading to misreads or faster battery drain. During installation, first clean the glass with a cloth to avoid dust affecting adhesion, then press gently for a few minutes to secure it firmly. Also, note that different car models have varying windshield curvatures; SUVs have more vertical windshields, so a slight adjustment can prevent glare and ensure long-term stability. Regularly check if the adhesive is loose, especially before and after the rainy season, to extend the device's lifespan.

When it comes to OBU placement, I emphasize its impact on safety, especially during nighttime or high-speed driving. The OBU should be installed slightly above the center of the windshield, right below the rearview mirror—this is the industry-recommended standard position. It ensures optimal signal reception without causing distraction or obstructing the view. I've seen many drivers place it off-center, resulting in delayed OBU response during vehicle startup or overheating alarms, which pose potential risks. Installation is simple: clean the glass and stick it on, but avoid doing so when the windshield is frosty in winter. Additionally, placing it higher prevents accidental touches by children or pets, reducing interference. If you frequently drive long distances, regularly check the device's secure installation to avoid mid-journey stops due to battery failure—this saves much more money than post-failure repairs.

As an ordinary driver, I'd like to share my experience with OBU placement: the best position is right in the center top of the windshield. I remember when I first installed it slightly off-center, which often caused issues at toll stations. Later, a technician suggested placing it closer to the rearview mirror, and the signal became much more stable. Choosing the right position saves a lot of trouble – if placed too low, it can block the wiper's line of sight and distract from driving. Also, pay attention to the device's temperature during daily driving, and avoid leaving it exposed to direct sunlight on hot days.
