Hi Everyone!!!

I'm new to the f-series family. I have a 2009 harley edition f-450(canadian model) with nav and dvd playback.

My question is the following.:

Is there a way to hook up a aftermarket overhaed screen for the passengers in back with the OEM head unit with the dvd playback.

My kids would be so happy...

Thanks guys and happy to be part of a big family!!!
