Wireless reversing camera - where and how to connect the receiver?

I have a problem where and how to connect the RECEIVER.
I connect to the 2DIN radio
When connected to a constant current from the 12v radio and in reverse gear, everything works. The camera image is there. However, when I throw back gear, it displays "no signal" on the radio screen, does not want to switch to the standard menu, but displays no signal from the camera all the time. The blue screen receiver raises the radio signal from the camera, even though it is no longer transmitting.

From what I noticed, there are sets with an additional monitor or GPS
I have the receiver below with an RCA cable and two cables (direct current and ground)
The only places that come to my mind are the sensor in the gearbox in the manual or if someone has an automatic (unfortunately not me) is under the "R" lamp on the display next to the jack.

Anyone have any other idea ??

The receiver is located at the bottom of the photo.

This is a problem of the radio, its settings or connection.

It seems to me that the receiver is well connected.

If you think it's ok then it's ok. Why are you writing then?

Please read with understanding. He does not need Janusz's advice, but only a person who has encountered such a problem or has relevant knowledge.

So stay Janusz alone with your problem.
Because Janus has already connected you, it is good, but it is not because another, or rather the same, Janusz claims that it is not. And the smartest Janusz writes on the forum only the type of radio he does not know, he will not insert the connection diagram. Instructions for it too. He knows so well that he put a picture from the web interface for connecting the webcam because it is this fault, although it is not. And yet he knows it. But he doesn't even know what and how he connected it.
So you got what you described. And probably another lamella of your kind will flash soon, they know how he did it on his radio.
Think carefully.

And when you disconnect the receiver, the inscription no signal disappears? If so, the receiver's power supply must also be connected in the same way as the camera's power supply. And the whole wireless system is ... worth it.

Where does your radio get the info to switch to the rear view camera input?
Do you need a cable from the reversing lamp bulb connected or a CAN interpreter that recognizes reverse from the CAN bus?
The mere delivery of the Composite Video - CVBS signal with an RCA connector is usually not enough to switch radio modes.
It all depends on the type of radio - unfortunately it's a secret ...

Subject solved. The receiver was connected to the current from the reversing sensors button, which appears when the reverse gear is engaged.

The connection diagram for this module looked like this - the red cable to the power and the black cable to the ground, nothing else.

This system is suitable for the automatic transmission to be connected to the diode with "R" otherwise connect the current from the fuses or the gearbox sensor, which is in the lead anyway and all its wireless function goes to the head ;)

Thanks for your interest and willingness to help
