What are the reasons for the restricted reversing assist system in the BMW 325Li?

[LorenzoDella]

BMW 325Li reversing assist system restricted reasons are as follows: Camera obstruction: At night, it may cause the camera's view to be blocked, resulting in a "Driving Assist System Restricted" warning. If it's also raining, this situation is more likely to occur. Installing a hidden dashcam, especially a low-end model, may block the light-sensitive camera on the interior rearview mirror. Some installers may also forget to remove the sensor housing inside, leading to this issue. Additionally, a dashcam malfunction or battery drain may trigger the warning. Applying window film or a car wrap may also obstruct the camera's view, causing the warning. The solution is to replace the camera with a new one. Radar abnormality: The radar may be blocked by foreign objects like tree branches, or a license plate frame may obstruct the radar sensor circuit. Deformation of the radar mounting position or a loose radar requires recalibration. The solution is to recalibrate and reinstall the radar.
