Ok, so check the filenames and the bit rates - if some tracks are in a different format then they won't be recognised. make sure there are no dodgy characters.

If you put the same CD into your PC, and then click on the properties of the file that will play, make a not of the characteristics and format, then do the same for the file (s) that won't...

In that case, speakers and amplifier are both working ok, so no need for the testing I suggested.
For the lack of radio, I can't help much. but do check it out on all wavelengths (LW, MW, FM...) and make sure a Mute button isn't getting pressed by accident.

That’s really interesting, do you have any pics?

Did you have to alter the wiring at all?

Ok so no, you cannot downgrade a firmware - not possible.

So it's a known fact that when you update to certain firmware versions, sou must get it calibrated at a dealer. They will need to connect to the PSA servers to correct certain issues and cure some of the problems that result from updating to major firmware. They will charge you a...

Good Job - that sounds about right for the diagnostic time, although a bit costly for what's involved IMO.

Hi i ask one question right now i have been told by a guy who i got software update from that the RT6 radio unit has a 10 year warranty true or false
False.

The only warranty is with the vehicle overall - 3 years / 60k miles unless you have taken out an extended warranty of course.

Nice one :)

Hi and welcome

Please pop your VIN up (automatically masked from public view) so I can see exactly what options your C5 came with. Then I'll be able to help you further. Some of these functions are contained withing a telematic unit and others without telematics may be fitted with an emergency services module (independent telematic unit).

Thanks Marc. I will give a reset a go.

The CD changers were not fitted as standard equipment on the Xsara Picasso’s - even on the Exclusives, but were available as an accessory, so they all should have the wiring loom there as standard.

They operate on the comfort VAN network, so make sure you get the correct one.

Hi Marc,
thanks for all your help and information, we have a local dealership so will give them a visit over the holiday
and see what they can do

best wishes

No worries.

Is this the Tom Tom system? If the update has been downloaded then signal strength shouldn't come into it. If it downloads as it's updating then it will depend on the signal strength.

Going on the SMEG+ system in our 308 that takes about an hour to an hour and a half for all the countries including western Russia. Each country (more accurately,...

You can unpair the camera - the only reason you really need to connect it is if you are taking pictures and uploading them to social media using your phone. If you are not fussed about that, then don't pair it with the ConnectedCam app.

The other purpose it is there for is for when a bump or an accident occurs where it takes a sort 30 second...

The actual maps are freely available from PSA servers. The 2019-2 maps are at and then you need an activation code.

PM sent.

Right, you don't have the SMEG digital receiver, you have a dual band RD45 unit.

So I would suggest getting a diagnosis with Lexia / Diagbox to see if the fault can be pinned down - but here is the aerial routing - but note you do not have all the options shown!

You only the following:
(1) AM / FM1 Aerial Base, (2) Aerial Wire,...

That was great info, everyone. Thanks very much!

Great - thanks for the update.

Thank you

Thanks turned phone off for 2 hours turned on works fine so just buggy

Good choice.

Could it be so that the rather pathetic stock subwoofer is protected on higher volumes, and it´s level is dropped in the additional amp.

I would scrap that JBL-soundsystem and install aftermarket amp and at least sub after original HU. Then you have to remove that JBL-amp with diagbox, after that I think you wouldn´t suffer this problem.

None of the changers are MP3 compatible - only the single slot in the head unit.

Thanks Marc, I was hoping to be able to use the existing cable for the now defunct Telematic unit (will return). Will buy an aftermarket sat nav. and hardwire it.

Again thanks for your help.

Mark

The head units in these vehicles tend to be of Fiat origin and aren't standard PSA units, so can't help you with a diagram I'm afraid.

The VIN is normally found in a small 'window' in the black area of the windscreen, down in the bottom left area, and is 15 digits long.

You could’ve got an aftermarket solution, such as an independent hands-free Bluetooth unit. This would’ve left the head unit intact.

That’s perfect, thanks for all the advice. Noted about the aftermarket HU, I’ll give that a miss.

All this for a bit of Bluetooth streaming!

A bluetooth receiver/FM transmitter would be a lot cheaper at a cost for quality.

Something like this .

Thank you, I have purchased a similar device that also transmits DAB radio. If I get on with...

My battery went flat & was like that for days, when I disconnected the battery & recharged the odometer stopped flashing - still no response from the USB or Bluetooth though

Guess mine will be the same problem, main delaers want £108 +VAT to investigate - more than the cost of a Parrot 9200 :/

:) I don't mind if I do!! Never had a bad time in Wales!! :-D
Regarding updating the maps if anyone has the 2010-11 map disc available for a loan or rent it might be handy!!
Just got to sort the passenger mixer flap and the headlight washer cover and I'll have a fully functional car!!
Once again thanks for all the help. =D> =D>

I suspect this is still related to the Head Unit issue in your other post.

Can you confirm you have replaced the original RD4 Head Unit into the vehicle and performed the reset I posted?

Well tried to have a look at the ariel from in side the car , removed the rear light in the headliner hope it would line up with the ariel base but no joy so I had ago at dropping the headliner at the back , partly removed a side trim but it started getting a bit to involved and lost confidence so put all back together again .....just was not...

I didn't mean you had to get some, just a heads up that some glass cleaners are unsuitable for display screens.

If you do want some, this is it

I recently lost the very good microfibre cloth that came with it, best one I have seen.

Ok, that clarifies. So not really suitable for your car - that screen will cover some of your console controls, like the heating control switches and may cause you to loose concentration when driving. Your choice, but I couldn't have anything like that - it just looks like it doesn't belong and simply stuck on.

I notice on their website that they...

You can’t just fit any old screen, there are significant differences between the MKI and MK II systems.

The original MK I had a VDO system, whilst the later MK II had the RT3 system with these colour screens and they are materially and connectively different.

Further, they can be VAN or CAN depending on the electronic architecture of your car....

That cable basically looks like it uses the CD changer port to provide the audio track only. Don't expect it to provide any other controls. As for coding, if not already enabled, you will likely need the CD-Changer option activated using PP2000.

Check out members with suitable diagnostics on the list: Link to Google Map of said locations at the...

Ok so on your 2004 model, you have an RD3, a precursor to the RD4. You also have the slightly older multifunction screen.

So the current RD3 unit is controlled by the ECU in the multifunction screen, which authorises the power on and off of the unit and the supplies.

So if you want to fit an aftermarket radio in, you will need to get a special...

Hi Jamie, you’ll still need to get it coded to your C4, plus you will still need to configure your vehicles’s BSI (main computer) to accept it and to configure all the other equipment options that may now be required due to fitting this unit.

I certainly would ask your local Citroen dealer first of all if they would be able to do this, because...

1 - Disconnect the battery. You mention a procedure. Would you please be able to let me know which is it? And the reconnect as well?
Never thought about a procedure with my previous cars. It was just disconnecting the terminals and that was it. I'll answer questions 1 & 4 together as it is essentially the same thing:-
Think of modern cars as...

Yes, the axillary adapter was recognised after connection without enabling as you suggested Marc - thanks Alex.

Ok, so a VIN will help in the meantime so I can determine exactly what you have.

i'll note the vin down tomorrow and update you. Thanks for your help btw, much appreciated!

I had also some problems to get steering wheel controls working with Kenwood HU. If I remember correctly, first I tried Kenwood´s own adapter that didn´t work at all, then after that it was InCarTec or similar adapter that worked partly, and after I sent it to manufacturer for reprogramming, it worked fine.

That Pioneer bundle Marc linked earlier...

Andalucia, 5km from the coast. 9°C at the moment, with a wind of 30-40km/h, so not so nice. The wind has been blowing for a week, much the same as the UK's icy spell. Ten days ago, daytime temp was 19-21°C, more typical for January here.
Log-burner doing its stuff; don't tell Gove.

Easy - the GS had the radio in the centre console, so didn’t have to reach, and as for those early ones, well there wasn’t anything to worry about as it was radio and cassette!😀 So no SD cards, CDs jukebox AUX, DVD sources to worry about Mike.

Anyway being a bit of a geek, I do admit to using the voice control a lot of the time as it can do just...

Post your VIN here so we know what system you have.

I've moved this to the telematics section.

Ok, well perhaps you need to check your settings as these are not always set to display speed limits, especially after any update, so may require rechecking.

Access NAVIGATION
on the screen, go to the next page
Select SETTINGS
Select ALARM
Select RISK AREAS ALERTS
Then from the available options, you should have one that says “DISPLAY SPEED...

No, they do a kit for connecting a non PSA head unit to the vehicle, but not this. You'll need something like these:

Line out converters.

Yes they did have CD changers on all Series I and II Xantias as optional extras.

Ah ok thanks for your help it was worth a shot :)
