Ok, so originally, your car was fitted with the RD4 system, which has a telephone interface unit, shown as item (28) on the diagram below:

Although there is a lot of kit on the parts diagram, you have only the following items:

(1) The RD4 Head Unit
(28) The Telephone Interface Unit
(32) USB Socket Harness
(36) USB Port
(40) Radio Telephone Microphone.

As for location on the left hand drive models it is tucked away behind the glovebox on your right hand side (passenger):

Marc may be able to dig out the wiring diagrams to give the existing and new pin numbers, but you may be able to find the information you need in this topic on installing an RD45 in a Peugeot 308: viewtopic.php?f=52&t=61437#p593499

Is it easy the get it out?
In my old C5 I almost knew everything but in C5X7 I’m a rookie... :-D :-D

Ok, so here is the guide for the glovebox for you - in 2 parts:- the lid first, then the glovebox itself.

Warning:- it highly recommended that you follow the battery disconnection procedure due to proximity of Airbags. Once you have moved the seats rearward (where electric seats are fitted), follow the relevant part of the procedure and again when refitting at the end. But allow 5 minutes minimum after disconnecting the battery to allow the airbag ECU power reserve to dissipate!

BSI Rest / Battery Disconnect / Reconnect Procedure

Glovebox Lid Removal
Slide the front seat rearwards as far as possible.
Switch off the ignition.

Be warned that the RHD car is not the exact mirror image. IIRC the door hinges are not for instance.

The operation is carried out in the same way for right-hand or left-hand drive for this operation Paul.

Not sure it will be of much use but I removed the underside only of the glovebox for the pollen filter replacement:

This shows some pics of the underside trim:

and a few pics here for the end piece removal when installing my dash cam wiring:

Yes I know, I was just pointing out it's not an exact mirror. It took me more than a few minutes to work out what to do.

So now I have located the box. Can anyone tell which pin-number I have to move directly to the radio.
The USB is quite easy. But what is the number for the microphone and maybe also for AUX, if this also connected in the box.

Have a lovely day guys.

And thanks once more for your help and support.

So the difficulty is that your car was originally fitted with an RD4 with the Nomad Hands Free Kit.
You have now upgraded to an RT6 (Telematics Unit).
So the Nomad Bluetooth Module is no longer required and should be removed as it might conflict with the the RT6.

The other issue now is the wiring diagrams are not 100% specific as you have a hybrid setup. I have done what I can to locate the microphone connections - but these are routed via an interconnection harness as you can see:
X7 Microphone.PNG
There should be a 3 pin connector in the microphone unit , but only 2 pins are used:
8487: Hands Free Positive +
8488: Telephone Microphone Earth

The interconnection should provide 2 connections into the a 12 pin connection shown.

Here is another look - the 2 connections in red are shown from the harness into the telematic unit connector in one of the 12 pin blocks on the (RT6):

Hey again.

Everything is just fine. I have moved everything and connect as it should be, but still no sound in microphone.

Do I have to activate the Mic from diagbox?

Sorry for so many questions.

You will need to change some settings in Diagbox for the Head Unit you have fitted. There is not separate microphone configuration, but as I said before, you will need to remove the hands free Nomad unit and also reconfigure Diagbox to make sure there is no hands free unit fitted. If not, the system might be trying to route the microphone output to the wrong place.

I'll have a look at the RT6 configuration for you - but have you made any other changes to options that were not fitted at the factory - I need to know or the configuration won't be correct. For example have you fitted any other equipment apart from the RT6?
