I installed an Alpine CHA S634 CD Changer with my factory head unit using a Peripheral HONIL interface and an Alpine KCA 130B. Everything went together perfectly, but when I turned the head unit on and entered the security code I can not get the changer to work. I put a CD in the changer, but pressing the CD button does not access the changer. Futhermore, when I insert a CD in the OEM headunit it does not automatically switch to CD anymore. When I switch to CD manually it says CD error.


Any Advice Appreciated

2. I did not switch changer from ai-net to m-bus, problem now solved.

Thanks guys
