Can anyone help? I have to manually connect my mobile phone every time I turn on my ignition as it does not manually connect. Is there an update or do I need a new head unit. Thanks in advance. :)
I should add that the unit is in a 2012 308....it's more frustrating than a problem.

Hi!
I have an 2011 C4 Picasso that came with a RD4 radio and no Bluetooth support which is less than ideal and would like to see if it's possible to replace the RD4 with a RD45. Most threads about this seem to be related to the models that have a separate smaller screen for audio functions while the Picasso has only 1 big screen. The current...

Hello ive been looking at getting a C5 X7 and as an hifi person id like to replace the headunit with something supporting android auto and bluetooth etc so i want to ask is this possible and if it is how should i go about it.
Thanks.

Hi , I've got a 2010 berlingo 1.6 xtr and was wanting to upgrade the small display screen above the radio . It is a red rd4 screen and was wanting a rd45, TYPE 4 or C (?) ,display screen as I am going to fit an android head unit. The makers say that the rd4 screen is not compatible with the unit but will work with rd45 .

Any foreseeable snags...

Hello everyone!

Recently I've ordered an RD45 from aliexpress for my Peugeot 207 SW (2013), but I'm unable to use the bluetooth function, because the multifunction display doesn't show the hands-free / telephone menu. So I was about to order a Diagbox to set it up, but I've read on the forums that the MFD software also has to be higher than V70...

Hello. I did the upgrade in one of the threads you linked. My research at the time told me that the screen HAD to be changed too, otherwise it wouldn't work. I'd like to link where I got that info from but it was a long time ago

Does anyone know of a 'Gadget' that will pair with two Bluetooth devices with one?
I want to connect my Phone and also a Music player to my RD45
Or is there another way Aux input?
Thanks

Hi, I have a 2015 DS3 with RD45 unit and can make and hear phone calls but can't be heard: the microphone doesn't work. The roof mounted microphone is present but there is no continuity between the microphone connector and pins 3 and 9 on connector B in the head unit (the microphone connections I believe).

The wires in the microphone harness are...

Hi

Thanx.

Yesterday a forum member very kindly enabled Aux 1 and 2 for me on my rd4 car stereo for my 2007 807 ( 100% happy with this) . I have added an aftermarket bluetooth player that plugs into part B and gets power from main plug, power is going to the stereo, the plug has 3 wires, the first is a black wire that appears to be a ground, this splits to...

Afternoon all,

Family member has a basic spec 3008 and the little barrel plug under the arm rear only has a 3.5mm AUX.

If I bought the barrel with a USB as well I presume it would work once programmed with Lexia?

My follow up question is how difficult would Bluetooth be to add to the RD4?

Thanks

Just aquired a 09 Citroen c5 2.0 hdi exclusive estate with just the normal RD4 radio without the bluetooth streaming/control, dab and rear view camera i wish it had.

Since i know and understand, that these units are not just radios but also control parts of the car im curious as what upgrade options that might be available on my model.

What...

Hello,

We have just purchased a Peugeot RCZ (1.6 GT) that is fitted with the RD4 head unit. We have been given different information from several sources as to whether it supports Bluetooth for audio streaming and hands free phone calls.

As far as I can see, the RD4 doesn't support them and that we need an external unit that plugs into the back...

Hello everyone, recently i upgraded from a RD4 to a RD45 on my 2008 C4 VTS and the parking aid sound is extremely loud, especially the rear. My car comes equipped with the amplifier and JBL subwoofer and CD changer. I also changed the screen to one with software v73 and every function works fantastic. The RD45 from what i can remember has SW...

Hi folks,

I'm posting here in hope one of you very kind fellow forumites may be able to offer some assistance with an issue I am facing with the radio tuner on my Peugeot 308 RD4 unit please?

The original factory fitted RD4 unit (single CD, single tuner) appeared to have developed a fault with the tuner a few weeks back where there was no audio...

Hello, I'm a proud new owner of a C5 X7,
After reading on here, and contemplating on what to do,
I have decided to stay with original equipment and only upgrade the existing RD4 unit and replace the busted display (pixels are burned out)
With the RD45 which includes Aux and Bluetooth support..

Now from what I can see, there's either Chinese...

Hi there, why would the sound be worst through the auxiliar than the FM radio?
There's no Bass when connected with aux, the sound is... shallow for the lack of a better word.
This head unit is from the C5 II.

Hi,
I’ve recently been handed down a Citroen C3 Picasso (2014) and it has for the most part been an alright car… until yesterday. I heard a loud pop and no sound has been coming out the car since. The word “SILENCE” appears when the radio is turned on and when a CD has been inserted, it gets stuck on the reading display. Please help as it’s very...

Hi users!

I have an issue with my radio/head unit in my c5 from 2005, the head unit is the Blaupunkt PSA RD4 X3 N1.
The issue is that it no longer responds to the numbers (radio station saved presets), or to most of the buttons, but curiously it does respond to the button band
which is on top of the button labeled dark , but when i press band it...

I have a 2009 C5X7 VIN VF7**************[VIN obfuscated, can be read by forum staff]
It came original with an RD4 radio. I stumbled on an RD45 radio. So plan to upgrade with this.

I have a Lexia tester, with lexia sw running on a win7.

I've run run in to the following challenges.

1. I can't seem to code the radio with the cars VIN. lexia won't recognise it, and it only returns ? in the...

Hi, new here!

So I have a C4 Grand Picasso 2010

Just had to have engine replaced and it was out of action for 7 weeks…

On return the radio is stuck in silence.

It has a mute button on the wheel and the radio itself and neither seem to do anything since the issue.

I’ve read something about a resistor needing to be swapped?

Other than...

I have an 08 Dispatch and someone replaced the radio with an aftermarket one. Without the Citroen radio you can't control the display. If anyone knows a way to set the clock so it thinks it is set and doesn't flash, maybe change the language to English as well, that would be nice. But I have a work around for the clock which is to prise out the...

Good morning People, I have a Peugeot 207 2010 1.6 HDi WA WC 112, the stereo cd wasn't working but everything else was. I got another head unit of ebay and got it vin coded it works, But now the bluetooth, AUX & USB Connection will not connect with the phone. The phones not the problem as it worked with the original head unit RD4/ RD45. As anybody...

So because the RD4 N1 is getting a litte dated as of 2022, I wanted to give ir a little more versitility. I already installed an AUX cable for the Aux1 port of the Blaupunkt RD4 Radio, programmed it with my lexia software and used it successfully. Now I bought a bluetooth module, which I already wired up into my car. The pins for AUX1 and AUX2...

Hi All,

I've just got hold of a carplay screen ( and so far it does exactly what I want (allows the use of Apple Carplay without having to change the head unit).

What I want to know is how easy would it be to either a) reposition the orange display screen lower in the dash (eg in that pointless gap just above the ashtray) or even better, move...

Hello. I have Peugeot 307, 2006. I have a problem with the dashboard/radio and date display. The display is completely orange and blank, nothing shows up just faded orange, sometimes it starts working from time to time but only for some minutes.

Hello everybody,

According to my experiences, my 2011 c5 x7 tourer has some weird noise when I try to listen music only from bluetooth or aux mode. When I press the gas pedal parallel to the rev increase there is some noise coming from the speakers whether music is playing or not. I think it may caused because of bad grounding. The car has its...

Hi All I have recently purchased a 2012 Citroen c5 exclusive with the RD4/RD5 unit! My previous 2009 exclusive had the RT6/WIP+ with the lager screen! What I wanted to know is if I could change the RD4 unit and put in the RT6 one with the bigger screen if I came across from another C5 ! Thank you

Hi guys,

1. How to check if my car (peugeot 207 2007r) has Nomade/Kml Telematic Unit? Is anybody know where it is located? And why some cars had it fitted and others not? What did it depend on? It is possible to check it by VIN?
2. I bought a genuine microphone because i didn't have one. I connected mic to mic harness (violet arrow) that was...

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 have just purchased a 2008 C3. It has the factory fitted cd/mp3 head unit but without bluetooth. I have a factory head unit from a 2011 207 which has bluetooth. Is there any way I can fit the bluetooth head unit to the C3 and get the bluetooth working?

Thanks
Simon

I’m trying to activate the AUX input on my radio with Lexia.
Problem is that as soon as I go in to the radio to configure it, I just get a blank line. Any clues why?

Hi there,

First time poster (and French car owner) here.
I just bought a 2009 Citroën C4 1.6l VTi VTS which I will be picking up the coming weekend. It has an RD4 unit (this is the standard unit right?), and I want to upgrade to a bluetooth RD45 unit.
What parts do I need for this upgrade?

From what I have read, I will need the RD45 unit, a...

Hi

Since I do not have the VIN of the donner C4 I wonder what else is needed but the LCD , RT4 and the associated harnesses. Looking at Citroen Doc Backup It seems there are two options
One without amplifier

Hi, i recently switched my RD4 to RD45 and i noticed two problems.

1. I lost parking 'beep' sound when on reverse gear. Parking sensor display works as before.

So I had something like this and broke, the truth is that for hands free was FTP? but for to listen musik from cel phone to RD4 was perfect to me .
Conclusion we do not go through it again nor do we make the effort to crouch if we find it thrown somewhere. .
I searched a bit to see what is on the market.

Hello, fellow forum members,

After reading up on upgrading from an RD4 to RD45 unit here on this very forum, I decided to go for it and ordered an RD45 radio, display and wiring from Aliexpress. The wiring and display arrived yesterday, but not the radio since it's probably held up in customs and I'll have to cough up import duty on that but I...

Peugeot 207 SW. 58 plate. 1.6Hdi.

It’s my thinking that you should be able to save 6 presets for each of the 4 wavebands.
E.g. FM1 could be for 6 radio stations, FM2 six different stations & so on for the other two wavebands giving 6 x 4 = 24 presets.

However, this doesn't seem to be the case. When I save 6 presents on FM1 they are also saved on...
