I think you'll find the control module is a complete unit - the circular unit that goes around the steering wheel containing all the controls. which would be quite expensive. I would use a bit of opaque paint (to allow the light to shine through at night) if you have a steady hand.

I recently installed what I thought was an RD45 head unit into my C3. It came from a Peugeot 207 with bluetooth. Unfortunately I found out it is a RD4 with a separate bluetooth module. I managed to find the bluetooth module (it was above the glovebox on the 207) and removed it. I also removed the aux/usb socket and the microphone from the car too....

I really wouldn't bother with it - get an RD45. The wiring is simpler and cuts out an intermediate stage.

Ok, so without getting the main menu up for the ECU,. you are not going to get into the configuration screen. Maybe your VCI is a revision B and not fully CAN compliant with missing hardware.

I am having intermittent problems with bluetooth on my RD45 on a '12 X7.

Roughly 80% of time it works normally, but sometimes when i start the car the unit does not connect to my phone. Phone not connected message is displayed all the time, even if i turn off the radio. When this fault occurs, I cannot access any submenu of bluetooth settings...

No problem, if you have the issue again in future, try each of the 2 methods - I know it sounds stupid, but it tends to work for most. :)

Is it possible to replace the original speakers with those of HI FI System? I have everything amp,suwoofer,speakers and wires.

Thanks for the schematics, but something is missing:
- the rear tweeters, where are the rear tweeters are connected too?
- the input in the amplifier from the head unit - from my knowledge the head unit doesn't have an output for the amplifier. So, if this is true from where I can get the signal for the amplifier?

Hi there, long time lurker, first time poster!

So I have replaced the RD4 in my '58' C5 with a RD45 (from a DS3), I used my Lexia to activate the fader for rear speakers and also activated the parking assistance etc.

My first question is about installing the microphone for the hands-free. I have removed the roof console an identified a two way...

That MIC may not have noise cancelling features - which is why I asked, so may be the cause of the issue.

If I remember correctly, on the 308 you need to also enable bluetooth hands-free (either in the BSI or screen configuration, I dont remember which) as if the earlier Nomad hands-free was fitted, so that the bluetooth screen display was enabled.

Yes you can code the RD4 Head Unit easily enough with Lexia for a 2005 C5. Run a Global test and then select the Head Unit ECU, select and go into parameters / configuration / manual configuration and the options should be there.

You can replace your RD4 with a RD45 that has Bluetooth for handsfree and music streaming. You will also require a new MFD or at the very least your current one reconfiguring.
