I am investigating which variant of RD4 and display are fitted and check what components would be needed to upgrade my 308 CC for RD45. The VIN is VF3**************[VIN obfuscated, can be read by forum staff] .

I previously did not think it worth the effort, but had a nightmare day yesterday trying to drive across town while people kept phoning me.

My 2007 Peugeot 407 has the factory fitted RD4 stereo.

I've tried searching the Internet and looking at various websites, but I'm only finding information for citroen cars.

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

Thank you.

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...

Good afternoon,

My aux cable has finally arrived for my RD4, when removing the stereo there is still an input slot available on the rear- which got me wondering whether you can get a cable to plug into an iPhone (or even my old iPod classic) so that I can control tracks from the steering stalk?

Or is it a case of the radio is too old and too...

Just obtained a Peugeot 407 Sport SW 2.2 HDI.

It has the non GPS radio unit. I think it's called the RT4.

Is there a place that's cheaper than peugeot to get the code?also if I pull out the radio to get the serial number will the wiring come with it so it doesn't disconnect, or is the wiring fixed meaning as soon as I pull out the radio I'll be...

Hi Guys,

I have a 2007 C5 VTR 2.0HDI and I am looking to install this Pioneer unit.

My car currently has a single CD unit, photo attached.
I am really struggling to understand which connectors/adapters will I need to install it as I want to keep all the steering stalk controls and also the controls for the little display beneath the...

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...

Hi

Anybody has the pin-out of the back connector of an RD4 head unit

Thanks

I have a Citroen C4 VTS make year 2006, that has screen C. I consider to upgrade the screen C to RD4 unit , do you know what parts should I collect to do that ( but the head unit, LCD screen and its frame ) , I guess I have to change the harnesses , what is the cat numbers of the harnesses and harness routing diagram . Any more information is...

The RDS on the radio (RD4) in my 3008 is not keen on re-tuning to another station. The RDS is working as it picks up the station and the RDS text comes through, and alternative frequencies is turned on, but it almost never changes frequency. Is this a 'feature' - never a problem in the similar units in the 307 or C4 Picasso so I think not? Aerial...

I have just bought a 2006 Citroen C5 1.6HDi 16v VTR estate and I am trying to figure out if there is a way to hook up an aux connection or a bluetooth connection (I don't have an owners handbook). I really only want to be able to play audio from my phone or tablet and be able to change the volume, not concerned about being able to change tracks...

Hi all

Sorry not been active, I've had an awful lot on my plate the last few months, most of it not happy.

Anyway, need some help please. Last night I tried to upgrade the stereo in my (now ex :( ) gf's C2 to an RD45 and it wasn't playing.
Installed the new (type C) display screen from a DS3 and that worked fine plug-play (nb: I've just realised...

Ok I know this may be a security related question, so if hecessary, can someone pm the answer if its something not to made publc. Is it easy to remove the radio? When I eventually get aother of these vans, I want to put my own radio in, which is better than the standard factory fitted item.

Like many before me I'm interested to know what options I have, as the lack of mp3 capability is unforgiveable for a 2005 model imo.

I've seen what looks like my RD4 but also has MP3 capability but wonder if there's something better that's also a straight swap and retains all the integrated functions (steering wheel controls, menu selections,...

Hello all,

I have recently become the very happy owner of a 2009 Citroen C3 Picasso which comes with what research suggests is the RD43 head unit ( has USB/AUX; I haven't yet removed the unit to confirm). However, I would really like to have bluetooth functionality for handsfree calling and I know the RD45 is capable of such witchcraft.

I have...
