Need Help with flip down monitor

[surferrepoman]

OK definitely not stock. I dropped it down and followed all the wires, it was spliced in everywhere. It actually has an old school limo antenna hidden above the headliner for regular tv! So I got power to the unit, hooked up a video feed from an external source, still no picture. The unit does power up but it looks like I need a remote to change the video source, which I don't have. Since the unit is aftermarket and wired everywhere I am taking everything out, including the miles of wires, and install a new unit. I will feel more comfortable running new wires in the vehicle too. Thanks for everyones input.
