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.

Hi guys ,

Here is an update.
I aborted the mission of finding the other end of wires comming out from pin 17 and 18.
I took an old pc , and i took the cable from power on L.E.D that is mounted on the motherboard. That cable has a 2 pin black connector so i used that connector to plug it in straight into the radio on pin 3 and 9. To plug this i...

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...

Nice work!

I'm doing some new speaker replacement my self and found this thread. Do you have a wiring diagram for the speaker wires? They seems to change colour between the door connector and the head unit. The factory cables is kinda tiny....

Hands free kit for C5 X7

First post

I own a C5 equipped with a RD4 radio that doesn't have the BT that enables it to serve as a mobile hands free. since I want to have the hands free option, I thought of the possibility to buy a RD45 radio and replace the existing one, but I think that it might be a little complicated (especially finding the right unit with the matching color panel...

Ok, I got that Avi.

My suspicions are confirmed!

This car was originally fitted with a standard RD4 head unit AND small standard Monochrome Level 'C' screen!

So the previous owner has at some point upgraded to one of the models I listed in my previous post - then after either an accident or scrapping it has decided to remove the head unit as it...

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.

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. The later screens were made by Johnson Controls and had a black case. I'd advise following Marc's suggestions and try and source a black one. To see the issues with the Borg units google '407 mfd'. It is more common...

Rd45 Peugeot 407

by vortexco » 04 Dec 2018, 16:21

First post

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.

Last post

I think this is getting a little too complicated for me.

I think I'm going to get a Bluetooth and dab rds transmitter. Not cheep but it'll give me Bluetooth and dab without losing any peugeot features by fitting an aftermarket stereo.

Thanks

RD4 and iPhone

by tomjyoutwit » 03 Dec 2018, 16:26

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...

Last post

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.

There are a few posts on the conversion on the forum.

Configuring RD45 via Lexia

by Jaguarr » 14 Nov 2018, 17:36

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

From what I gathered when I did the same upgrade, I had to make sure the software version of the new screen was at least v.70

I've never seen a screen in the Picasso, but it appears to be a EMF-C embedded in a gauge cluster. If the EMF-C is still accessible separately in Lexia, then you will need to activate the handsfree options ,amongst others,...

I won’t use Aliexpress so cannot advise about them.

As for the last link, no. That is RT3 System and needs the larger scree. It does not support Bluetooth or USB, so forget that one it is even older.

Sluggish RDS

by RichardW » 02 Oct 2018, 20:27

First post

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...

Last post

Do you know if the radio has (ever) had its firmware updated? This sounds like just the sort of thing that could be cured by an update. I don't know for sure if there's an update, I'm just fishing!

The main computer controls these units by sending digital data signals through the different networks. They can can stay on for a while after the vehicle is switched off and locked.
