It is possible. Hell, almost anything is. Just depends on how much effort one is willing to put forth.
You'd have to find out what format or protocol (ID3 Tag, etc) the factory system used to 'read' that info. Find where the data wires or pins are for the display. Map them to a serial port (or some kind of output) and send that info from your media player in that format... I think that's how it goes. I'm guessing really.
