So I have come to realize that my bose headunit doesn't have a cassette player, and some headunits didn't. I am basically looking for anything that would like to trade oem headunits because I need the cassette player. My Bose headunit would be exactly the same as your bose headunit, except without the cassette portion. I looked online at pictures. Mine has the 6 cd changer and everything just not cassette.
