I welcome everyone! We need to solve the problem. After buying a Chinese radio, I decided not to pull and immediately connect it. After connecting, I found that everything works except for the buttons on the steering wheel. Having traveled for half a year, I decided to climb up again and connect the buttons, in addition I decided to reconnect the rear-view camera from the mirror to the radio. The result is half a day lost, the buttons do not work. Also, when you turn on the rear, a black screen is displayed with a message about the absence of a signal. Additionally, I found two incomprehensible connectors.
1. 1 wire for the camera comes out of the radio, 4 wires come out of the camera - how to make friends?
2. The wires coming out of the radio are working, I put them on the signal contact when adapting the button, it sees everything, it programs the button. But nothing happens from the required 20 pin connector. Please help me figure it out, it's a matter of principle.
