Phone Mute for PCM on 03 Turbo

Recommended Posts

Hi all

My wife has just acquired an 03 cayenne turbo (04MY to complement my 996 cab).

I have previously installed the nokia bluetooth kit into the 996 (pre MOST) and wired the phone mute to pin 3 on connector A. Bingo! radio mutes every time the phone is used-very convenient.

The PCM however is very stubborn. I have read various posts on this site and others (rennlist) that suggest that pin 3 on connector A will work also mute this unit when it is grounded

However I can't get it to work. I have eliminated the car kit my manually grounding pin 3, again no response from the unit.

One point is that this car does NOT have the phone module in the PCM, just a blank SIM drawer, and as far as I am aware no phone prep (it was always an option on euro/Australian spec cars). Also the unit is the early CD type, not the newer DVD type.

I suspect that the phone mute function might need to be "turned on" as is the case with some of the other becker head units. The mute does work from the multifunction steering wheel though, but I assume this is actuated via MOST.

Can anyone shed any light on this function as it is driving me mad!
