I have a Bose Wave Music System with add-on 4 cd changer attached. The top portion (radio & 1-cd function) is working fine. The 4 cd changer is not working, I keep getting an error message and none of the 4 slots will play cds. Is there any way/ any place to have this repaired without having to buy an entirely new system?

I had a similar problem. No discs would play and sometimes they would not eject. I solved my problem with the crevice tool on my vacuum cleaner. I vacuumed out all the openings on the unit, especially the cd slots. This discs now play and eject.

Bose does not release their schematics or parts lists, effectively making themselves the only repair center for their products. Your only safe repair method is to contact the service/repair center at www.bose.com. They will likely offer you a flat rate repair or credit towards the purchase of a new unit.
