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.

Configuring RD45 via Lexia

Hello all
So I've bought RD45 replacement for the old RD4 to support BT music and phone in my Grand Picasso C4 2013.
I was able to configure the radio to work well (added the VIN to the radio using Lexia).

However, i can't see any option to enable the screen for adding Bluetooth menu.... as far as I know, I have screen type c and it should...

Last post

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.

Ok, so from your description, it sounds like you have a basic RD4 system and additionally a hands free audio unit that is fitted behind the dash.

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.

Judging by the fact that the rear casing is white I would guess this is made by Borg. If this is the case, don't bother, it will die.

My 2007 Peugeot 407 has the factory fitted RD4 stereo.

Is it possible to fit a RD45 to my car so I can have Bluetooth audio streaming? Mine is the grey stereo.

Thank you.

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.
