PCM Pinout Question

[pb1302]

I have looked at the PCM 2 pinout diagram and notice that there is a Microphone hook signal wire on it. Is this were you would tap into for a MUTE feature? I have a IHF1000 that came installed in my 04 CTT but of course it does not mute the stereo. Is there a way to take the MUTE signal from the Motorola unit and hook it up to the PCM? It has the BOSE package with the MOST fiber running to the amps of course. I would just like to know if it is worth buying this cable to have that feature - Bluetooth Radio Adapter

Thanks for the reply. What sheet 19 and E Handy telephone connector are you referring to? Also my PCM is WITHOUT the telephone feature so will this even be possible to do?

Sheet 19 in the 2004 Cayenne schematics. All US/Canada car had telephone prep with a mute line.

How do I get these schematics? Can you help out? I don't have access to a Porsche dealer near by.

You can download them here for $1.80 per page (last time I got them that was the price).

PM me if you still have problems.

Just tried this out. IT WORKS.... I just jabbed in a wire to test it in the A plug (bottom one on back of PCM 2 pin A3). Called the wife and the radio said TELEPHONE IN USE and muted the radio. :) Ended the call and 2 seconds later radio back playing some tune.

Thanks for your help Loren. When I get a chance I will post up some piks and a write up for those that want bluetooth adapters installed in their cars and the radio to mute. I know its just a lazy way to turn down the volume but it is HANDS FREE after all.
