SOURCE: I have a 6 CD Changer but dont know how to use it?
This is an older way that makers of CD changers used to get CDs into cars that didn't have them. This is what they tried to get people to by them. I was never a fan of this system as the sound quality was never better than listening to FM radio. There is a unit in the car, usually under the dash behind the glove box, that the CD changer is plugged into. This unit has the FM antenna from the car plugged into it, and then a cable that is the same as that coming from the antenna going from the unit under the dash plugged into the FM antenna jack of the radio in the dash. All this unit does is take the digital, high quality sound from the CDs, transmit it on an FM frequency (usually low on the FM band 80s, 90s or low 100s) and then you tune the radio into that FM frequency to get the sound form the CDs. Problem is, the sound quality was only as good as FM radio. A pretty poor way of getting CDs into cars. But they sold millions of these things. If it isn't working, the wiring may have come loose, the fuse to the unit under the dash might be blown, or something is disconnected. if you go all through the FM dial, 0.1 at a time and don't hear it, it is time to get under the dash near the glove box and poke around. Good luck. If it were me, I would take all this gear out and put a new CD/MP3 player where the factory radio currently sits.

Try resetting the CD (Cambridge soundworks) by unplugging, then repluging. Then hold down the eject button while you turn on the power.

if it really doesn't work - it is almost impossible to fix. You would be best off calling Bose for a return authorization. They have a one-price repair program (they essentially toss your old unit and send you a reconditioned unit). Look for the Customer Service -> Factory Authorized Service links on www.bose.com for phone number or e-mail address. They will also give you advise how to fix your problem before they suggest you send it in - a very good program.
If it just doesn't make any sound, you may be in a remote area with a weak signal (or part of a house with a weak signal). To remedy, make sure the power cord is untangled and hanging free (The FM antenna is sometimes in the power cord). Also, check the back of the unit, if there is a small connector for an antenna, you could add an antenna. Even a piece of thin copper wire works (about 6 ' long and pulled straight - horizontally or vertically.).
Good luck.
I buught a Mitsubishi M-VR700, which produced no audio from the speakers, but with headphones, a tiny bit of audio was detectable with the volume control on max. This solution was posted on FixYa by Mojorisin65 some time ago: Facing the receiver directly behind the MITS logo & power button is a vertical board with a large IC on it, try flexing the board near the IC while turning the reciever on & off or changing input modes, there is a cold solder joint on this board which I haven't found yet. I understand this is a common problem with the MITS M-VR700-900, Onkyo TXDS-575, & Integra DTR5 or DTR5.1 ( all made by Onkyo).
I gently flexed the board as described, and Boom, all the audio was back as it should be. I suspect Mojorisin65 is correct about the cold solder joints, but with SMT components, it could be very difficult to find. I may very well be on one or more of the 48 pins on the large IC. This IC gets rather warm during operation, which may explain why some units may work until it heats up. The chip gets warm and 'twists' enough to lift the bad pin(s) from the circuit board. In an attempt to deal with this symptom, I superglued a TO-220 heat sink to the top of the IC (don't let it touch the case of C-716). The heat sink is dissipating a fair bit of heat, and so far, this 'fix' seems to be doing the trick. RJD 10.18.11
