Chinese GPS with AV/IN.

There doesn't appear to be a control to use the AV/IN. Anybody know how to use it?

I think I had one like that. The unit auto-switched to the rear camera when it sensed input from the a/v line.
So happily showing maps then slip the car into reverse and the screen would display rear camera input.
I would imaging any video source would trigger the same behavior.

Thanks for your suggestion but nothing I have been able to do from any video source will trigger it with the GPS in any state of operation. I have to conclude it's a dud. I was hoping to use it as a larger screen to monitor the output from my DSLR when shooting on location.
