Hello, I have been having problems with the return camera and the display in the display for some time now. When the reverse motion is inserted, the switching signal and the signal (pipepen) will sound faster when approaching. However, the installation (radio) in the display remains unchanged. So no display of the camera. I was in the workshop today and we set the display (Genration1) to factory suspension and, in test cases, also blocked the battery for a few minutes. ra for testing and the master also had no solution ready. I just want to mention that I was on the highway at the beginning of January with snow and Glatteis and was the next day in the washing system with underbody protection. About since then the camera picture does not turn on. Unfortunately I also do not know which camera is installed, but the master was so friendly and has picked out a part number: 957902S012 There are also very cheap far east models, but I do not know if the Border lines (green-yellow-red) are also displayed and whether someone has already built these parts? Unfortunately, I didn’t get any further in the other forum and therefore I ask for support here.
