I made a cable connection to the top right socket with 3rd pin to camera video line, 5 and 6th pin together to the camera ground.Took 12volt connection for camera module from the reverse light and grounded camera to the vehicle body. now the MMCS and camera is connected. But when i put the vehicle in reverse, the reverse image is not appearing on screen.But when i go to the camera settings menu, i can see the reverse image.is there any connection left to be made?when i check the "network line settings" in the mmcs by using set+navi button, all are showing OK(camera,GPS,dvd...) except video in. is there anything else to be done?
