Rear camera don't work

dudu-lai

Juras Is the camera connection to CVBS-IN1 normal? Have you tried replacing the F cable?

I was told the DUDU7 would work with my factory rear camera but only get a black screen when I put it in reverse

Neckbone What type of car? Have you connected the yellow tulip (RCA) that comes from the harness provided with the unit to the cable in the picture above? The cable in the picture above should be connected to the F connector on the headunit. I have a Corolla Hybrid and it really worked out of the box with the factory rear camera. If you get a black screen it means that you didn't connect something correctly. The unit doesn't get signal from the factory camera.

MihaiFlorin it’s a 2019 ram 1500. I do not have anything to plug the yellow tulip into. I have these that I have tried to connect but nothing happens

Juras

I connected only yellow wire.

You must connect this connector to something similar that comes from your power harness.
What you are trying to do using only the rear camera from the 360 is not the right thing. Things don't work like that. In order for the 360 cameras to work properly you must have all of them powered-connected. You should have another yellow RCA connector that says CAM VIN or CAM IN. After you connect the yellow RCA connector make sure that in the Settings-Vehicle-Reverse camera you select the Reverse camera option not the 360.
Also taking a look here will help.

Neckbone Then you should get on the telegram group. And more than sure @dudu-lai will help you there. You should have a yellow RCA coming from the power harness provided with the unit. Here on the forum the communication is a bit hard.

@Juras @Neckbone This is a power harness for a Corolla hybrid (just as an example)
and as you can see it has a yellow tulip (RCA) labeled camera. This connector must be connected to the other yellow tulip (RCA) that comes connected to the F connector on the unit.
From what I know all of the adapting harnesses have something like this but I might be wrong.

Neckbone

MihaiFlorin I do have both yellow connected

MihaiFlorin

Neckbone I see you have another yellow connector. Can you tell me what it says on its label?

Neckbone

MihaiFlorin I did also try that other yellow tulip as well. I can’t remember what was written on it.

MihaiFlorin

Neckbone Then get on the telegram group. I cannot help you further, sorry.

Be sure if you need 12V or 3V for the original rear camera power supply.
If it's 3V then plugging into 12V will burn it out.
It is recommended that you replace the rear camera with a new AHD camera.
