My friend has this - - Pioneer DVD Receiver with MP3 and Dual Zone Capability Model DVH-P5000MP

and wants to know if adding this -
Lessco: Car Audio, Speakers, LCD Video, Keyless Entry, Remote Start, Alarm, Security System, GPS

will allow him to stream videos from his ipod to his setup.
He has the older version where a external screen is needed, its not the flip out one.
He has the external screen and wants to know if the videos will show up on the external screen or not.
