What Causes the Black Screen of BMW's Reversing Camera?
1 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.
