[CHRISS3]

hi guys need help asap im in the process of getting an audi navi system for my s3 i need to know how much hassle it will be to connect a dvd player to it as im told the unit itself does not play audio cds, has anyone done this with an amp and a sub? will the cd info come up on the screen ?
thanks
