EONON GA7151 and rear-view camera Mazda 3 2004.
Sorry for my English.
I have a problem with the GA7151 Mazda 3 2004.
I have a rear-view camera.
It is connected to the corresponding video connector on the GA7151.
When turning the reverse gear on, the GA7151 does not switch to the camera.
The camera is operable and turns on when the rear speed is turned on (checked on a separate monitor).
On GA7151 there is no separate wire, where you could send 12V, to inform about the inclusion of the camera.
The GA7151 also does not switch to the black screen when reverse gear is engaged. That is, the GA7151 does not receive information from the CAN bus about the inclusion of the rear speed.
The rest of the CAS bus functions work. (I installed the display from the restyling model, it correctly displays the time and other indicators of the computer.) There are buttons on the steering wheel).
I'm at a dead end.
If anyone can suggest a solution to my problem, I will be grateful.
