I have an 8000 NEX. I just installed 1.11 with seemingly no issues. I then installed a front camera on my truck. I have set the AV input to Camera, but the AV input does not show up on the source list, so I can't select it to use it. I know the camera is functioning, because I can select it in the Picture Adjustments menu, and I can see the image it is producing.
I don't know if the problem was there with the old firmware. But youtube has a couple videos showing how to set it up that were made a year or so ago. And it worked then. I'm wondering if they broke or deleted the feature
