I have a customer who just bought a 2002 S40 from me. He did not get the Volvo 10-disc changer as he did not want to spend the extra $$$. Now, he is having a hard time in finding a compatible changer for the car, he finally found an Alpine model but where he is getting it from they are telling him that he needs to purchase some kind of a wiring harness from us which, in my mind, is a bunch of baloney. The car is already CD-prewired from the factory. We do not sell anything that can make that CD changer compatible to our end of wiring. Any ideas? Any CD changers out there that may be compatible for the 2002 S40?
