[Solved] Rear View Camera No Signal - Troubleshooting Peyiyng Opel Vectra C, PY9908 Radio & Installation

Hello colleagues, this is my first post. I hope you will help, to the point. I installed a reversing camera in my vectra c in the frame of the board, power supply (+) from the reverse light cable (ground) to the lamp screw. Then, of course, "czincz" to the radio (peiying py9908) to the purple plug (back view in) and the red cable that goes with the czinczem to the radio, I connected to the orange cable from the radio cube. This is how it should be according to the cube diagram, I turn on the ignition, the radio starts, the music is put in reverse, it enters the camera mode and the message CAM NO SIGNAL. I checked the cables again, etc., but everything is fine, there is one more yellow chinch with the inscription View In from the radio, so I connected the chinch from the camera to this entrance and then the same. However, when I unplugged the red signal cable (the one that goes to the radio with the chinch) from the orange one, the camera works, but you have to enter the camera mode manually from the radio menu and only then it is ok. every time you reverse, switch on this mode yourself.

summarizing :
when the chinch from the camera is connected to the purple chinch from the radio (back view in) and the signal to orange on the radio, the camera mode enters automatically after throwing backwards but there is no signal

when the camera is connected to the yellow czincz on the radio, it is probably called (view in), the camera mode works, but not automatically, and connecting the signal cable to the orange causes no signal

I put a problem on the radio, but I prefer to be sure. Regards and thanks in advance.

Try to give independent power to the camera, maybe the signal from the reverse is sowing and the radio does not detect the signal.
