Where to place the OBU device?

It is best to place the OBU device one finger's distance away from the top of the glass. The specific steps are as follows: 1. After receiving the product, first check if it is intact; 2. Once confirmed, log in to the YueTongCard APP; 3. Click "Apply for a new YueTongCard, My Orders, Order Details," then click confirm receipt; 4. Click self-service activation, and you will see the installation instructions for the OBU device. Follow the prompts to install it; 5. The electronic tag should be installed on the upper right side of the rearview mirror, near the passenger seat. Clean the installation area before proceeding; 6. Press the electronic tag firmly with your hand during installation to ensure it does not easily fall off. At this point, the installation is complete.

I generally recommend placing the OBU device right in the center at the top of the windshield, approximately behind or beside the rearview mirror. That's the golden zone because it offers the best signal reception without being blocked by sunroofs or metal. Once, I took a shortcut and stuck it slightly to the left, and on the highway, the ETC recognition was painfully slow—I was almost stopped by the toll collector. It wasn’t until a technician repositioned it to the center that the issue was resolved. Also, avoid installing it on tinted or cracked windshields, as this can interfere with GPS positioning. I suggest cleaning the glass surface thoroughly before installation to remove dust and grease for a stronger bond. Regularly wipe it with a damp cloth to keep it clean and prevent signal interference. In short, the right placement ensures convenience, cost savings, and safety.

To install the OBU device, I usually choose the upper middle area of the windshield near the rearview mirror. Signal reception is crucial, and placing it there ensures quick detection at toll gates. When I first started driving, I didn't know better and stuck it too close to the passenger side, resulting in frequent false alarms or failures. It took me a long time to figure out why. Some vehicles may experience weakened signals if the windshield has coatings or obstructions. It's advisable to check if the glass is smooth and free of obvious scratches before installation. Daily maintenance is simple—just wipe off dust. This ensures seamless toll collection and avoids unnecessary hassle or fines.

The OBU device is best placed at the upper center of the front windshield, near the rearview mirror. This position ensures strong signal strength and smooth ETC gate passage. When installing, make sure the glass is clean and unobstructed, avoiding areas with dark tint or metal objects. Signal issues commonly arise from improper placement.

I recommend installing the OBU at the top center of the windshield, near the rearview mirror. This area provides the most stable signal reception, ensuring the ETC system operates accurately. Once, I installed it slightly off to the right corner, and the GPS positioning kept malfunctioning, causing delays at toll booths. During installation, avoid areas with windshield defects like cracks or tinted film zones. Keeping the position centered helps minimize failure rates.

I mounted the OBU device right in the upper center of the windshield, next to the rearview mirror. The signal reception must be strong there to efficiently handle toll stations. I make it a habit to clean the device surface weekly to prevent dust buildup from affecting its functionality. Incorrect positioning can lead to slow recognition or toll collection failures, which is particularly annoying on highways. It's recommended to wipe the glass with alcohol before installation to ensure no grease remains, and choosing a flat, interference-free spot is crucial. Daily maintenance is easy and convenient, making it both safe and reliable.
