Where is the suitable position to install ETC?

ETC is suitable to be installed behind the central rearview mirror. ETC is an electronic toll collection system used for automatic toll collection on highways or bridges. It is a service function of the intelligent transportation system, composed of an automatic vehicle identification system, a central management system, and auxiliary facilities. The function of ETC is: through dedicated short-range communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane of the toll station, using computer networking technology to conduct background settlement processing with the bank, so that vehicles can pay highway or bridge tolls without stopping when passing through highway or bridge toll stations.
The most suitable installation location for the ETC device is on the inner side of the car's windshield. Generally, placing it behind or beside the rearview mirror is the best choice. Personally, I recommend positioning it slightly to the right side as it is closer to the window for better signal reception without obstructing the driving view. When I installed the ETC in my car, I specifically chose the right side of the rearview mirror, carefully cleaning the glass area to ensure no dust or film would block signal transmission—otherwise, it might fail to read at toll stations or even be stolen, affecting usage. Remember not to install the device where airbags deploy, as it could pose safety hazards in case of an accident, and also avoid direct sunlight to prevent premature aging of the internal battery. During installation, follow the manual instructions to securely adhere it without shaking. If the position is off and the signal weakens, simply readjust it—it only takes a few minutes to ensure smooth driving on the road.
