Sorry for the late reply due to the Chinese New Year's Day.
Could you please first tell us your order number or product SKU?
Did you buy the rear screen from us?
For the rear screen connection to our unit, it's easy, supply power for the rear screen, then plug the corresponding video in/out and audio in out RCA cable, then the video on the head unit will display on the rear screen.
