I am in need of some major assistance regarding my 2002 C230 Kompressor with a standard stereo. First of all, i would love to buy a CD changer that fits in with the factory system, but I have a few questions. First of all, what type of installation is reuqired, when I look in the glove box of my car, theres no hatch or hole with wires for anything in it, unless i am not seeing them... Next will I have to reprogram my onboard computer to work with this player. Also what brand and stock numbers are compatable. I am also wondering where the bose subwoofer that goes into the hatch in the side is available. We have a bose store in our mall, and they don't seem to have it. Also what is the stocknumber and whats involved in installing it. Finally i am wondering what replacement tweeters are available for the system. All complete answers would be appreciated, and please Post everything, I have read through article after article of poeple E-mailing the instructions, and i think it would be more benefical to post em. So thanks alot folks for your help !!
