This is a common problem with Factory Bose/Clarion 6-disc changers.
The gears to load and switch CDs are made of plastic that will eventually get
brittle and crack or strip out.

I have also sent emails to corporate and working with the Better
Business Bureau and the State Attorney General's Office for a
resolution.
