Why does the retrofitted BMW reversing camera not display?

[JackDella]

The retrofitted BMW reversing camera not displaying is due to poor wiring contact or prolonged usage. Poor wiring contact: It is necessary to promptly inspect the wiring connection points with the vehicle's installation to check for any loose connections. If present, this will naturally cause abnormalities in the reversing camera display. In this case, simply securing the loose connection will resolve the issue. It could also be due to aging of the video power cable. Trying a new power cable may solve the problem, indicating that the video power cable was indeed faulty. Prolonged usage: If the reversing camera still does not display after checking the above two scenarios, it is likely due to the prolonged usage of the reversing camera, resulting in poor chip photosensitivity. This not only causes a snowy screen but may also lead to a black screen. Another possibility is a defect in the vehicle's circuit design. However, issues like chip abnormalities and design defects are beyond the scope of DIY fixes and require inspection, repair, or replacement at a professional service center.
