I tried this for my 2013 with the 8 inch screen no GPS. On mine you dont have to go to menu to choose DVD set up, And when you are to press "back" there is only an X to go back, not like if you go further into the setup, where there is a back arrow. I tried what I thought might work from what was said here but no joy. Had audio but no video. Have they fixed the trick to bypass this? Also has anyone tried to feed from the usb port back say to a monitor?
