wassup all, ive been interested in getting a dvd player for the the CLS. Im a total noob in regards to dvd info. First off, is it possible to use the stock HU, with stock speakers, buy a dvd player from ebay, connect it to the an lcd monitor via RCA plugs, tap into the stock speaker wires, tap into a power and ground source, mount the lcd into the headrest, and voila movies w/ sound from the speakers?

sorry im a total newb.....

thx in advance.
