French Car Forum

Greetings from Germany,

I have replaced the built-in RD4 with a RD45, installed a hands-free microphone and I am quite happy with bluetooth and hands-free operation.

2 things bother me a little:
I cannot access the audio settings (bass/treble etc.), the menu is greyed out.

Languages available on the device are Chinese, French and English.
I...

Can anyone tell me what adapter I need to connect my RD4 to a USB input please?

At the moment the cigarette lighter socket has a USB connector in it's place but the type A USB wire from this just goes up behind the dash and is not connected to anything. Therefore I don't even have a 12v supply to the cigarette lighter so no power socket for a...

My 2008 207cc has an RD4 and an EMF-C with v51.?? firmware.
Got an RD45 in the post this morning and an EMF-C with the later firmware is arriving next week.
Thought I'd give the RD45 a go and the first obvious thing is that the RD4 (and the loom) have White and Grey antenna connectors and the RD45 has just the White.
Connect the RD45 and the White...

Having got used to Bluetooth on my partner's C3 Picasso (it has an RD45) I'd kinda like it in my 207cc.
So firstly I considered replacing my RD4 with an RD45 but my multifunction display is only on 51.something so that gets a little more complex.
Next up is the 'Nomad' unit...
Question is, do I already have one?
My radio is griping about an F905...

Hi,
I'm sure it was asked many times, but i have to ask one more time. Is someone able to provide me with straightforward instruction / guidance to how to change rd4 to rneg in my 2009 c5?
Thanks,

Hi,

I have replaced a radio in a Peugeot 207 with a radio from a Citroen C3. It powers up and plays the radio fine, but is constantly beeping every few seconds as it needs programmed.

I have an Autel that I tried but it can't do it, does anyone know what diagnostics will be able to program the radio to this car?

Couple of issues. C3 Picasso 2012 with the audio system and the 'Monochrome Screen C'.

Trying to delete the previous owners phones with 'Delete a paired device' and when selecting a phone it just returns to the main screen and doesn't delete.

Next, pairing a new device with 'Perform a Bluetooth search' finds my Samsung A12 then immediately says...

Hey there,
hello from newbie. I've been already visiting here for a while and been learning about my 2011 C4 B7 for a while, but now my first thread.

I happily replaced the RD5 (aux only) in my B7 darling with the RD5 L5 (with aux, usb and bluetooth) .
Everything...

Hi, so I thought of upgrading the radio but read on the forum that you can loose some steering wheel functions, is it just radio lever functions or cruise control / display lever where you can check mpg economy too ?
I have the dispatch enterprise 2014 Vin: VF7**************[VIN obfuscated, can be read by forum staff], thank you.

Hi,
This is my first post here :)
I have a plan to replace my RD4 with RD45 radio (I need USB and BT). I already bought RD45 (version with black front plastic in attachment) from aliexpress but a little different version.

The first thing is front plastic... I tried to change it but it does not fit, the only solution is to break the plastic...

Hi all. I have C5 iii 2008 16v 2,0 lt engine. I brought it as used june 2022. Looking for aux in my Rd4 unit I see cables coming from connector part B, pins 1,2 and 7 towards the interior of the car. However no sockets for aux founded either in glovebox or in the box between the front seats. In the radio menu aux input can't be shown. Is it...

Enquiring for a friend. The said friend has a 2012 6 cylinder model. Is the Continental RD45 model likely to suit his vehicle.

Hello and good day, sorry for reviving this old tread but this is beautiful

Good afternoon all....I am looking for someone who can help me with my radio and mfd problem.

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

Hello
I have recently bought a 62 plate C4 Picasso which I am quite enjoying in a relaxing way!

While it is much newer and higher spec than any car I've ever owned before, there is a glaring omission - the stereo doesn't do bluetooth and I'd like to play music and make phonecalls.

The stereo in it is, I believe, an RD4. Comme ca:

FWIW, the...

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
on my c5 x7 the multifunction display has a problem. there is a bright spot on the middle of it and the info is (very) hardly visible. since I have the mfd from my previous c5 mkii, I would like to know if it's compatible with the one fitted in the x7? pic of the faulty mfd attached.

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...

Hi guys can someone help me out if i tell the VİN number of my car wich radio original compatible is with my vehicle? İ know there are different types of RD4 and RD45 car radios on the market. How can i be sure? İf it was possible to upgrade to RD45 i've noticed this two different part numbers on this radio. RD45 L3FA04 CEM00 and RD45 L5FA04...

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 all, my EMF-C display is unreadable at this point and needs replacing.

69AEE95C-4842-40EE-9623-B652B7B8F547.jpeg

Only problem is that breakers and sellers on Aliexpress are looking for ridiculous money (£70-100) for second-hand units. As I'm quite frugal :-D I was wondering if it's possible to fit an EMF-A display (as these can be had for...

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...

I doubt this information is worth anything, but here is a list of the different RD45 models I've seen for sale:

- RD45 L3FA04 CEM00 - right CD button says TA - Tunisia - SW 3.0.0.13
- RD45 L3FA04 CEM00 - right CD button says TA - Tunisia - SW 3.2.00.06
- RD45 L3FA04 CEM00 - right CD button says TA - Tunisia - SW 4.1.01.00
- RD45 L3FA04 CEM00 -...

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...

I am trying to upgrade my C5x7 with an RD45 radio.
