No, because these original telematics units in the vehicle have to use a permanent live all the time, hence Pin 12 on Part A.

As said, it's been reconfigured by somebody - it's the only way this can happen. Settings have been changed that are leading to the loss of functionality. I'd be pretty annoyed to be honest as they had no business doing anything like this - and I'd be demanding some reparation to get it fixed.

However I am willing to assist on the basis you are...

I'll sort this for you tomorrow when I have a bit of time.

No guarantee that reapplying the firmware will resolve anything if it's an internal issue or the hard drive is failing, but it won't cost you too much to do a CF card replacement as per the guide to see if this resolves it. Note: CF Cardc is recommended as it uses a compatible ATA command...

The first connection is the main 12 way connection to the unit and the second is the LVDS connection.

If these are all in place then either you have a faulty NG4 or it has not been configured correctly for your specific vehicle options - parking assistance, equaliser amplifier, services module etc. etc. All these...

What was the new antenna that you bought?

Yes, just find some you can bear and overwrite them.

It's a legal requirement unfortunately and if you ever got caught or had an accident, it would have serious implications for insurance and personal liability if it was found that this was the cause. It's why CarPlay and Android Auto have to block any video playback apps from their systems.

As it's a legal and safety issue, we can't facilitate any...

Here you go. :wink:

The system reads DVD Discs from the built in DVD player via the slot.
MP3 files or WMA files can be played from the SD card or USB.
Video can also be played from the AUX-In port in the glovebox, but can only send video signals to the screen from devices like a camcorder or games console or other device that can output a video out signal using RCA...

Please don't create duplicate posts as it causes duplication of answers. I've deleted your other thread on the Citroen Forum, so please keep all replies here.

Hard to say whether this will be the hardware in the Head Unit, the Display Screen, or the LVDS cable between the two.

No worries - once you have a SIM card in, when you go into the phone menu it allows you to select either Bluetooth or internal phone. As you already have the Bluetooth phone selected it will just continue to use that, but the annoying SIM message will go.

V F 3 is Peugeot V F 7 is Citroen, so that would also be a reason. Glad you have it sorted and thanks for the update.

So I can't help you as this vehicle has obviously had the NG4 above retro-fitted and was not standard.

Therefore there will be a loss of functionality for sure because a lot of these units also rely on a 'services module' for emergency calling and assistance. As you had the RD45 fitted at factory you don't have the SIM socket which is part of the...

@Red69Devil, PM sent.

Thanks!

I can’t advise on an aftermarket unit. I only support original systems.

Some here have fitted an aftermarket ‘Joying’ Android system, so you’ll have to have search on the Forum.

Thank you for answer

Hello, i have same problem on my Citroen c5 2010, no visible satelits and poor localization, every repairer wher i go said to me that it is posible to be problem with unit.
Sorry for my bad English xD

Ok, so here are the main pinouts. The Microphone is in 'Part 'b', however, be aware that your vehicle, like mine has the service module installed. This is essentially similar to an independent telematic unit (similar but not the same), so for emergency services (SOS and Citroen Services) functions to work it uses the SIM card to make these...

Gotcha. Thank you Marc. :)

Leave the synchronise with GPS box UNTICKED. Ticking the box can cause issues with the GPS N Week Rollover.

What map version have you installed?

@GiveMeABreak:
Thanks Marc, you help me a lot with this!!! youre great! thanks again.
Kees.

Yes, the SD card slot at the bottom front of the Head unit is specifically for playing media files - but they must be in the correct format.

Make sure you are using a normal SD card formatted with FAT32 (I used a 32Gb card). MP3s need to be between a speed of 8 Kbps and 320 Kbps and WMA need to be a speed between 5Kbps to 384 Kbps. Variable bit...

Where are the Maxi Fuses 4 and 5 located? Are they susceptible to damp or dirt?

The Equaliser Amplifier (if fitted - as this was an option only) is located front left in the dashboard as I have circled in yellow:

aMP.PNG

so that will be up on the roof rail at the rear near side inside the headliner. thanks for that

Not possible natively Matt. The video source in the glovebox is for peripheral equipment like camcorders, games devices cameras, portable DVD etc. etc. The system is not designed to switch to video using reverse gear not to accept a reversing camera. The unit has a speed sensor so blocks any video when moving at anything over a snails pace.

I...

Thanks Marc.

Sounds like she’s going to need to get over the little orange screen then :D

Hi Marc

Thank you for your help so far. If you could help with the fire wall update that would be great.

Ainsy

Thanks Marc,
Sorry for the delay. I appreciate your response.
Yes the pic you have attached is the system installed in my 2012 C5.
The car was exported to Victoria Australia. It is a C5X708 MY12 Exclusive HDi VIN: VF7**************[VIN obfuscated, can be read by forum staff]
I have now taken a pic and will attach.
I still love the car, the suspension is absolutely fantastic (even better...

Ok, so I have just checked out that message and there is a Technical Service Bulletin relating to that exact message.

Basically, the Flash Memory on the motherboard has been corrupted and PSA's solution is to replace the whole thing.

So If you have a spare NG4, you will need somebody with Diagbox that can code your vehicle's VIN into the...

Cheers Marc
Appreciated

Those wiring codes don't correspond to anything I have - probably why they were cut Martin.

What did you do? We'd all like to know!

Ok, that must be a coincidence as the NG4 has nothing to do with the Climate control unit - none of the readings or functions are related to the unit at all as the Climate ECU is a separate unit and will still function even if the NG4 unit is removed.

I suggest for now you just select the temperature you want and set it on AUTO and it will do...

I cloned my hard drive (to save it from wear) and use an SD Card now with IDE adapter and have less issues and faster start up.

I change only the lcd screen. The ECU is the same.

It might be Google maps and the App specifically with frequent voice instructions - so may have more or less kept the HF going so no music.

It's at least an alternative if you are desperately in need of Sat Nav though.

MyWay is in the same boat as NG4 and it won't be too far on when RT6 support fizzles out too. This being down to the horrible touch screen affairs that they are shoving into the newer models that use mobile apps and subscription services that need 3G / 4G data to work - so if you live in the country / rural areas with limited mobile signal, yet...

Definitely no backup battery, as all the data is stored on the hard disk and in the flash memory. The only battery is in the services module as I mentioned before for emergency powering of the speaker, the microphone and for the actual emergency call.

I still suggest you try a reset of the unit, and if you still have problems a factory reset....

Hi and welcome.

Do you have the NG4 (Navidrive 3D) or the RT4 system?
The pictures for each are in the Audio & Telematics Main page here and will be the second or the third picture.

If you have the NG4 (Navidrive 3D) the system is likely going into backup mode because of the temperature inside the unit. The official causes are listed as:...

Sorry - only just seen this post.

The NG4 system is dependent on having the correct equipment other than the head unit and also must be VIN coded AND configured to the vehicle using Diagbox / Lexia.
The NG4 is designed to work with the MDS Service module, which is linked to the Microphone and the Head unit via the CAN system. So unless you got...

Can't be done - the USB will charge the phone and will play WMA and MP3 files on an actual USB stick directly, but will not play files from an iPhone's music library. You can also use the SD card in the Navidrive 3D to play the same - which is what I do.

You can connect video or audio sources to the AUX socket in the glovebox - and select this as...

Righto RT4. All the firmware is supplied as standard with the OFFICIAL map updates as part of the package, bot OP has got a used kit with some of the discs missing it seems. I think he's sorted for the firmware now, fingers crossed on the map update now!

Something on the lines of this.hope you can see image..

There's a very good reason for it - the NG4 system doesn't support Bluetooth music streaming! It does just about everything else though, hence why I suggested it. You have to remember this was a 2008/9 system and probably designed a few years previous to that, so they can't support every future development of Bluetooth. They did provide several...

Of course the other great thing with the SD card is there are no moving parts - so with less disk activity, the unit should remain cooler. You just have to play a DVD and see how hot the unit gets! Regarding the SD card - I have a 32GB SD HC in there and haven't managed to fill half this yet. I haven't tried anything bigger, but don't see an issue...

I feel another VAB-size topic coming on with this project!! :-D
