I have a TSX with NAV, and I want to play an MP3 player through the sound system. I would rather not use a modulator. Does anyone know what kind of connectors are in the back of the head unit and is there an adapter available? Also , has anyone taken the dash apart yet? What is involved? I used to do intallations, so I could just get in there with my tools and try, but maybe someone has some advise?
