What Causes the Black Screen of BMW's Reversing Camera?
2 Answers
The reasons for the black screen of BMW's reversing camera are: radio malfunction, host unit malfunction, or accessory circuit failure causing the reversing camera to display a black screen. Radio malfunction: First, check if the radio and video playback are functioning normally. If not, it may be due to a radio malfunction. Reversing camera circuit failure: If other functions are normal, try pressing and holding the volume power button, then restart the host unit and test again. If the black screen persists, it could be a host unit issue, or problems with the reversing camera probe or circuit. It is necessary to visit a 4S store for inspection and repair. If the host software is abnormal, a software upgrade may resolve the issue, or relevant accessories may need to be replaced. Accessory circuit failure: If the original vehicle does not come with a reversing camera, the issue may be due to accessory circuit failure, problems with the added probe itself, or incompatibility between the added reversing camera and the vehicle's system. In this case, it is necessary to have the added reversing camera inspected at the installation shop.
I've driven BMWs for many years and encountered the reversing camera screen going black several times. The most common cause is the rearview mirror camera being covered by mud or leaves, resulting in no display. Once after rain, I wiped it clean and it restored. Another issue is loose connection cables, especially after driving on bumpy roads, which can easily detach and require re-plugging. Software conflicts, such as failed system updates, can also trigger a black screen, which can be resolved by restarting the car's infotainment system or visiting the dealership for a software reset. Hardware problems like damaged camera modules or display malfunctions are less common but require professional inspection. Don't delay repairs; ensure clear visibility while reversing for safety first. Regularly cleaning the camera during car washes can effectively prevent such troubles.
