Ok, answering to my question , all you need to do in order to replace your CD500/DVD800 unit with an android one, is to use a CD400 button control panel, and cut the purple wire from the display (14:45 at the video) and connect it to the second empty pin slot at the connector plug (16:00 at the video).
