Bluetooth Installation; PROGRESS Report

Recommended Posts

Hi All,

Brief History, in 2005 My custom ordered Cayenne included the telephone prep kit. This was the hard wired handhold mounted unit.

Looking to upgrade to Bluetooth, if I can work out ONE bug this install would be LESS THAN HALF AN HOUR (for those with phone prep option)

I bought a Parrot LS3200. Using a wiring harness ($30) I was able to;

Hook up the AUX in speaker wires to the Parrot

Hook up Constant +12 V

Hook up the Ground

Hook up Switchable +12 V

Hook up the Mute lead

Hook up the Car Microphone


The unit powered up, the PCM recognized the Bluetooth unit and displayed "EXTERNAL PHONE ACTIVE"

I made a call, the PCM muted the radio and the call went out over the car speakers.


The car microphone did not seem to work with the Parrot, despite being the same size plug the caller's voice quality was mechanical and unintelligible. No problems using the Parrot supplied microphone. SOLUTION is to use the Parrot Microphone.

The mute feature did not disengage after the call was ended. In fact, once the unit became active it muted the stereo.

Any thoughts how to resolve this mute issue? Do I need to pull the head unit out and connect it there?

The same mute lead works properly with the Hard Wired Porsche Telephone system.

I'll post detailed photos and installation instructions when I work this out.

I am very interested how you solve this. I have a 2006 Turbo S with the 9PZ option for the PCM which is the handset wired into the vehicle. I am trying to figure out how to configure it to operate from by cell phone via bluetooth. Let me know your solution or problems.
