Coverage and how to read this overview

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.

POST 1 / ORIGINAL POSTEROriginal post

First little job on my recently acquired C2 was to fit a Renn Classic hazard light phone bracket. In doing so, I discovered that I have what appears to be a genuine Porsche microphone behind the little grille [that I needed to remove to lift up the dash top instrument cluster]. The car has CDR-23 and Bose. Nothing about a phone kit or PCCM. No obvious related cable behind the HU or climate control. While I haven’t (yet) tried tracing it back, I’m puzzled as to what it’s for - unless this is the microphone for the Bose volume adjustment? Any thoughts? TVM!

POST 2Original post

Yep, I should think that’s for the Bose AudioPilot noise compensation system. The microphone gauges the cabin noise and adjusts the hifi output to compensate.

POST 3 / ORIGINAL POSTEROriginal post

Thanks, that was my first guess, so I’m assuming this will somehow work with PCCM+ should I ever get that far

POST 4Original post

Yes, you should be able to plug the mic into the head unit, I believe it’s essentially the same part that would come with PCCM+, same connector etc. Yours is actually the perfect location for the mic and I had to take my dash apart to replicate this on my own (non Bose) PCCM+ installation.
