Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

My 2003 996 C4S came with the M680 option, the Bose MOST radio/amp, but not the front-trunk-mounted CDC-4 CD Changer. Is adding that changer a simple plug-play operation (i.e., is the wiring harness for it already in place behind the trunk linings)?
You must have one that is MOST bus, not an older one. I have one in my 04 Targa that is not being used as the radio was changed out for aftermarket. My factory setup was CDR-23, BOSE & cd changer make me an offer Look and see if you have the optical connector. I believe it is orange (could be wrong)
Clarification/expansion of my question: The car has the Bose CDR23 head unit and the appropriate amp down in the trunk next to the compact spare. If the car had come with the CDC-4 CD changer (which is what I'm considering adding), the changer would have been connected by the fiber optic MOST cable to the amp and head unit. The wiring diagram (as best I can understand it) also shows a DSP (I believe that's a digital signal processor) wired into the above combination of audio pieces. So far, do I have this right - and if not, where am I off. And wiring them all to each other (presumably with the fiber optic MOST harness), can anyone describe that harness.
Why are you looking to add a CD changer? Finally upgrading your 8 track collection? I'm honestly baffled.

If you have the DSP, it is in the center console. I believe that was an option as an alternative to a BOSE system Yes, the CD is connects via the MOST bus and is a fiber optic cable. Ill look at my CD changer and amp in the morning and see how they are connected together or ??? Since there is only 1 connector on a CDR-23, it either splits or the CD and AMP are in series
