You're going to have to improvise, probably going from the roof console out to the windscreen headlining and down the A pillar into the BSI area through the end of the dashboard panels and through into the centre console to wherever you're intending to connect it.

A word of caution though - do not wire anything in front of the A pillar wiring or in front of the right and left sides of the headlinings in the roof, as this is where the curtain airbags and their igniters are stored. If these go off and you have wires in front of them, it will act as cheese wire and have the potential to cause serious damage to anything in it's path.

Huge piece of advise! Thanks a lot for that warning! I'll let you know of the result when done.

The diagram above show the microphone (#8242) has 2 wires which run (in the harness) to the original hands-free box (#84B4) pins 8 and 9. If you locate that box with the 18 pin blue connector under the dashboard (on the left, near the head unit), you can extend the wires from there.

If you do run a new cable, you should be able to follow the path of the existing wiring harness by unclipping the A pillar trim and the removable cover on the end of the dashboard. That is what I did on our 308 CC (although I know the trim on that is different to yours).

Hello. The problem with aftermarket units is that they do not supply the bias voltage through the mic jack as on the original units.
The microphones in our car require it, as they are electret. I have a hi-end Android unit and it still has this problem.
My solution is a pre-amplifier with adjustable output, connected to the original mic, such as https://whadda.com/product/universal-mo ... -wsah1803/, placed as close to the mic as possible. Mine is in just over the mic in the roof.
I am also working on a wiring, that can supply the 5V for the electret capsule, but not back to the unit.
