Comand 4.0 reverse camera - no singal
I enabled the camera from the Engineering menu (SRVC option). When I select the R gear the screen switches to the camera screen. But screen shows black. Can somebody help me? What I am making wrong?








Your TV still has video input analog style one ? Those yellow RCA jack kind of composite input ?
Its very rare to see those input nowadays.
If the reverse camera resolution too high, maybe the NTG4.0 would not want to show the image.

Something came to my mind. Does it possible to make the opposite test. To connect the car multimedia video input with some other device, for example home DVD player that has analog output?




I have a rear passenger 2 video screens at driver and co-driver headrest. MB original. And a DVD player too at rear set middle part, MB original. None is a 720P resolution.
Model year 2014 is my car.

Well, that is a good test to do.
