Why is the reversing camera not responding when shifting to reverse gear?
2 Answers
When the reversing camera does not respond after shifting to reverse gear, it is generally due to the head unit freezing. Here is the relevant information: 1. In this case, you need to restart the head unit and then try shifting to reverse gear again. If the reversing camera still does not respond after restarting, it usually indicates a malfunction in the head unit. This situation requires a visit to a repair shop or 4S store for professional inspection and repair. 2. Poor contact in the wiring or switch of the reversing camera: If the connecting cable between the camera and the car display comes loose, or if the switch of the reversing camera is damaged, it can cause the reversing camera to not display. This situation requires reconnecting the wiring, and if necessary, replacing the switch with a new one.
Last time when I shifted into reverse gear on my own car, the rearview camera didn't show anything. After checking for a while, I found there could be quite a few issues: The most obvious one is the rear camera lens being obscured by dust or rainwater, making the image unclear; loose power cables or blown fuses could directly cut off the power supply; or it might be a software glitch in the infotainment system that requires a reboot. In my case, simply wiping the lens clean with a damp cloth did the trick, or sometimes driving around for a bit allows the system to reset automatically. Don't underestimate this function—it's crucial for obstacle avoidance while reversing, so safety comes first. My advice is to try simple fixes first when you spot an issue, and only visit a professional shop for wiring or module checks if those don't work, to prevent minor problems from escalating into major ones that affect driving. Also, making sure the rear cover is sealed tightly after parking can help prevent malfunctions.
