Apologies.

Hi Rusty2009, thank you for answering and sorry about late reply.
Why i have believed it is CD450 is that guy who did divorcing and VIN coding of HU. HU was bought on eBay.

Picture 5)
Here is an image.


Picture 3)
I have managed to feed wire from mic seated in roof panel around and down to central console.


Picture 3, 6, 7 and 9)
I used 2x1 core wire as female connector on mic gives me wires output of 2 BUT input is 3 wires comming from microphone, as sen on pic.


Picture 4 and 10)
I was guided by this to find correct pin on harness connector taking pins 6 and 20.


After completing it i have got no joy. Microphone is not working. I can hear other side speaking with on car speakers but that person cannot hear me.
Tried swapping a wires 6 to 20 and 20 to 6 position. Nicht, nada.

What it went wrong?
Thank you in advance
