I have completed the conversion, and it all seems to be working. I will go back in with Diagbox later and double check the settings, as didn't have the recommended settings data with me when I first did the set-up.

To clarify what I did with the front panel, the RD45 came with a Citroen front panel, and was made by Continental, my RD4 had the glossy black panel that is special to the 308 CC and RCZ. My RD4 was made by VDO and although the major mechanical dimensions are the same, the internal details of the plastics and PCBs are significantly different. The multi-way connector between the front panel and head unit is identical, and in the same place. I ended up completely dismantling both panels, to swap the Mute button onto the RD4 panel, then fitted that panel (with the RD4 PCB and plastic-work) to the front of the RD45. Electrical compatibility has now been proven.

When first installed I tried disconnecting each antenna in turn, to check that they were both contributing, but found that there was no signal coming form the antenna with the grey connector. I repeated the test this morning, and both were able to provide a good signal. I think that during my first test, the tuner with the grey connector must have been doing a background RDS scan, and thus not listening to the station I had selected.

To reinforce what others have said, the bluetooth functionality requires that the NOMAD function be enabled in the EMF-C display configuration.

When I took out the trim above the windscreen to fit the microphone, I found that there was already a (vacant) connector for a microphone, so my car had been pre-wired for an external bluetooth box for the RD4. There is a spare blue connector below the glove box which I think may be the other end of that. I used the stand-alone microphone cable that I had ordered with the RD45, and although it cam with a connector 'B' for the quad-lock, I popped out the pins for the 2 wires and put them into the existing connector 'B' to retain the analogue Aux in (one thing I have not tested yet).

So I can now listne to music from the radio, the CD, the analogue input, the USB stick, or streamed from my phone. It can get a bit confusing. The bluetooth streaming quality seems OK BTW.

The Green "digital" antenna input on this RD45 is not much use for DAB (or anything else) because it has no centre pin, and is apparently not connected to anything inside the head unit.

I have found one issue: There are now double warning beeps, e.g. from the parking sensors, one from the radio and one from the beeper in the dashboard. I am sure it is caused by some configuration error, but I can't see anything relevant.
[edit]
Fixed the double beep. there is a setting in the BSI to enable/disable parking sensor beeps from the controls under the steering wheel. That had got changed, probably when I attempted (unsuccessfully) to run the procedure to de-install the RD4.

Hi. I have done this change to my 308 from 2009 and i have a small issue with the microphone and aux1.
So i had RD4, with Type C display , and bought RD45 , and activated from Diagbox the BT function on the display. The seller coded the radio for me ( Vin no ) so i just plugged everything back on the car.
I can connect my phone to radio via BT , i can stream music from phone to radio , i can play music from USB device , but when i make a call via BT, the other person can`t hear me. I checked the rear of the RD45 in the B connector and i have 6 wires , which looks like they are AUX 1 and AUX 2. Pin 3 and pin 9 are empty. I opened the light cover from roof, and there i had an empty spot for the mic and 1 white connector for the mic. So i mounted original microphone in that hole and plugged the mic in the white spare connector. As i saw on previous page , from the roof the cables are going to A pillar in one connector , and then from there they are going into another Blue connector under the glove box. The question is , after the big blue connector from glove box where the cable is going ? I can`t see nothing behind the radio. Correct me if i am wrong : On the blue connector behind the glovebox ( where you open the fusebox cover , first blue connector from left side ) pin 17 and 18 should be from the mic on the roof. Pin 17 should go to Pin no 3 and pin 18 should go on pin 9 on the back of RD45 in B side. So i might have 2 situations. 1. In the blue connector pin 17 and 18 will be empty , or in pin 17 and 18 i will have cables which i won`t be able to trace them :D.
I wouldn't want to buy another mic with cable and route everything to RD45 unit.
So these are 2 problems i am facing with this upgrade. The mic i can understand for the moment why it does not work, but the AUX 1 should work because was working before.

Thank you.

The microphne cable from the roof will be terminated at the connector which is there for the OEM hands-free kit. These wires would need to be extended to reach the RD45. I decided that it ws easier to buy and fit a complete microphone harness, although that requires re-pinning part of the quad-lock connector because the mic pins are adjacent to those for Aux 1.

The Aux 1 input option must be enabled in the RD45 configuration, and it probably isn't (as most cars have either USB or Aux 1 but not both)

So the wires should be visible as a spare connector or they terminate in the big blue connector that has about 20 pins?
Also, as far as i remember from yesterday the aux1 was enabled in radio but still no sound comming through.

Thanks

Ok. Found the plug with 20 pins. Took the multimeter and checked the wire continuity from roof to that plug. And yes that's the plug. Pin 18 and 17 is the same as pin 1 and 3 from the roof plug. But the question is , where those wires goes ? Is a brown and green wire on pin 17 and 18.
EDIT: I removed the glovebox so i can trace the cables better. I found that from pin 17 and 18 the wires are going in a big loom of wires which goes behind the a/c controls and from same loom exits another 2 looms. 1 is going to hazzard lights , esp and lock/unlock doors and another one it goes to cd player. Then i followed more and i found a spare connector same type as the one that goes in hazzard lights controls but it seems that are other cables not the one from the mic.
I saw on previous page a wiring diagram but i think that is from cars fitted with rd45 because from the 20 pin connector underneath the glovebox it goes straight to part B in RD45. But for cars fitted with RD4 i understand the mic cables might go into an aditional bluetooth box but i couldn't find any diagram where that box should be mounted maybe i can find a spare connector somewhere there.

Thank you

Hi guys ,

Here is an update.
I aborted the mission of finding the other end of wires comming out from pin 17 and 18.
I took an old pc , and i took the cable from power on L.E.D that is mounted on the motherboard. That cable has a 2 pin black connector so i used that connector to plug it in straight into the radio on pin 3 and 9. To plug this i had to remove the white plug with aux cables , so no more aux1 , but anyway wasn't working with the new rd45. Then i tapped into the wires coming out from pin 17 and 18 and voila ! Microphone working , crystal clear sound. If i will have time and effort to make it properly i will do it , but for the moment will be like this.
Another way to do it better would be to take out pins from aux 1 out , move them to pin 3 and 9 and the other end of wires which is in the glovebox i could have unplugged them from rca connector and tap them into pin 17 and 18 from 20 pin connector which is in same place ( glovebox ).
