Recently i've bought this Android device together with this reverse camera .
Looks like all the connections was made properly, in the back the RCA connected to the RCA and the red power wire from the camera is connected to the red wire that coming from the RCA (the ground is not connected to anywhere)

In the front the RCA is connected to the RCA and the red wire from the RCA is connected to the wire "back" (as the seller said).

More available wires:

12v
360 cam
...

Also the system settings are set to the right parameters (the selected camera is "Modified reverse mode")

The problem is that when i put to "R" i just getting a complete black screen with guiding lines and the parking sensors info and nothing else.

I've tried to do a Factory Reset, Update Version nothing worked.

Maybe some of you guys knows what can be the issue in this case?
Any help would be appreciated.
