Where is the Honda CR-V reverse radar buzzer located?

The Honda CR-V reverse radar buzzer is located under the cover behind the rear seat. Reverse Radar: The full name of the reverse radar is "Reverse Anti-Collision Radar," also known as "Parking Assistance Device" or "Reverse Computer Warning System." This device can determine the distance of obstacles and provide alerts about surrounding obstacles to enhance safety during reversing. Buzzer: A buzzer is an integrated electronic sounder that operates on DC voltage. It is widely used in computers, printers, copiers, alarms, electronic toys, automotive electronic devices, telephones, timers, and other electronic products as a sound-producing component. Buzzers are mainly divided into two types: piezoelectric buzzers and electromagnetic buzzers. In circuit diagrams, buzzers are represented by the letters "H" or "HA" (older standards may use "FM," "ZZG," "LB," "JD," etc.).
Last month I helped my neighbor fix the reverse radar on their CRV, and the buzzer was actually quite hidden. In older models, it's usually located under the dashboard on the driver's side, near the fuse box. When I opened the cover last time, I found it secured with screws—a small black square box. The newer models are even trickier; the buzzer is integrated into the instrument cluster assembly, making it completely invisible from the outside. If you notice the radar sound is unusually muffled or suddenly stops working, it's likely this component is faulty. When checking it yourself, remember to disconnect the negative terminal of the battery first. Using your phone to record video under the dashboard is the easiest way to locate it—last time I did this, I found the issue in just ten minutes.
