PSA NAC RCC Updates

[GiveMeABreak]

If using a MAC, you should be aware that there may be system files placed on the USB that may or may not be visible which can affect the process. Here is the firmware that includes the maps and your licence file:

Firmware 42.03.33.42_NAC-r0

Licence File


The process is explained here with a method of removal - I can't help you directly with the issue as I don't use Macs, but this may be useful. Or you may need to use a PC. Bear in mind these extra files are HIDDEN, so you won't see them on a MAC! But they will likely affect the update process.

Any file that begins with ._ isn't an image. When you copy files from a Mac to a drive formatted as FAT32 or ExFAT, the Mac OS creates two files. One is the data, and the other is the resource fork information written as a separate file. It has to do this since the drive formats mentioned don't support a twin fork file system, so OS X has to save the resource fork data a different way. You don't see them from your Mac since anything that begins with a period is automatically hidden.

So if you copied a file name hillside.jpg to a FAT32 or ExFAT drive, OS X will create these two files:

hillside.jpg (the actual image)

._hillside.jpg (the Mac resource fork data)

A free and pretty easy way to remove the ._ files is to use Terminal. I'm going to assume a USB drive for the following.

Plug in your flash drive so it appears on the Mac desktop. Open Terminal and enter:

dot_clean -m

Enter a space after the -m .

Then drag and drop the icon of your flash drive into the Terminal window. It will fill in the path of the drive. Press Enter. All ._ files will be removed from that volume.

Be aware it will remove all ._ files. Including those that actually may be data, such as the resource fork for Mac Type 1 PostScript fonts and Mac legacy TrueType fonts. If you remove the ._ files for those, the fonts will be destroyed (no data left).

Dear Marc. I will try. Thank you. Can you just check the first link with Firmware and Map since both a leading to license file?

[GiveMeABreak]

Sorry about that, should be fixed now.

Hi All,

I have issues with my iPhone and CarPlay on my Citroen C5 Aricross 2019 (My wife's iPhone works just fine, though)

Would love an update file if possible.

My VIN is VR7**************[VIN obfuscated, can be read by forum staff]**************[VIN obfuscated, can be read by forum staff]**************[VIN obfuscated, can be read by forum staff]

Thanks!

I also have problems with carplay not working or disconnecting at random, where these also your problems and did a software update fix the problem?

[GiveMeABreak]

That’s likely to be a cable issue not a software issue. Use a good quality Apple certified cable.

I have tried different original apple cables. Tested the cables in my Volvo and they give no issue. So I can only assume it is a car/software issue.

All cables have the problem that after some time (can be 1 minute or 30 minutes) the car stops recognizing the iPhone and shuts down CarPlay. The phone stil sees the car and says it is connected but nothing is shown in the car screen (CarPlay icon is grey). A disconnect a connect does not work. The only thing that works to get CarPlay back (before it stops again) is a full car system reboot. It is very frustrating

Hi Marc,

thank you very much, now my firmware version is 42.03.33.42!

But a map update did not work. The system informs me about the map update and lets me select map-eur and start the update, but shortly after that an error message "map update cannot be performed" appears. Now there is no map in the navigation function, and that view indicates that an update and map installation is required. I tried to reset the NAC settings but it didn't help.

I got the map installation to work when I downloaded 42.03.33.42 by Citroën Update.

Have I understood correctly that now the system should be wave 4 type and have a possibility to continue updating the system further?

[GiveMeABreak]

Yes, that is a bridging firmware that converts your system from Wave 3 to Wave 4 and you will now continue to update with wave 4 firmware.

The latest Map for you is V16 Here

So you can reformat the USB and install this now.

[Darko512]

Sorry about that, should be fixed now.

Dear Marc,

Thank you for the info. I have tried but without success. When I put USB in the car nothing happens. I have tried with different versions of map (12 then 15 then 16) different USB... Strange thing is that when I do via Citroen update app it immediately recognize that I need to update software plus cartography and USB is recognized but it offers Software version (42.03.33.42_NAC-rO) that car already have? Software is installed but maps keep failing to instal. Can you check what version of the Software is shown for the VIN Number VR7**************[VIN obfuscated, can be read by forum staff]? You said that the maps are from 2018 but i dont know if you can check the software version of the infotaiment system on some server?

Any help to solve the issue is appreciated.

Officially the software you already have is the latest shown for your system.

Unofficially, there are several later firmware versions for your vehicle:

44.02.13.12_NAC-r0 (March 2022)
44.02.16.52_NAC-r0 (April 2022)
44.06.44.22_NAC-r0 (Dec 2022)
44.07.05.22_NAC-r0 (Feb 2023)

So I've included the actual link for the latest Wave 4 firmware (the last one). Maybe if you try this first, then the map update again, you may have better luck.

Thank you Marc. I will try with this new version. Can you alse share the License file for that version?

[GiveMeABreak]

Sorry, I just realised you don't have an independent telematic unit fitted, so no WiFi, so these updates won't be any good to you!

I can only provide licence files for the officially provided firmware versions via my system. I can't get licence files separately - so as the only firmware being offered is the one you have installed and that is therefore the only licence being generated.

If you had an independent telematic unit with WiFi, then of course you could of installed the later firmware as the licence would be generated automatically OTA.

[Darko512]

Dear Marc,

Thank you. I have WIFI option and when I connect it says no services available (probably I am not subscribed to any I told you just recently purchased the car) but there is a wifi option to connect. In Car Vertical it says that the car is equipped with AUTONOMOUS TELEMATIC MODUL 3S. So do I try to install and then after installation try to connect to internet?

Also, are maps related to OTA generation or?

[GiveMeABreak]

My bad - again! I have so many requests I had the wrong VIN, so yes, of course you have the C5 Aircross and yes, you do have WiFi, so that should be fine - you don't need to connect to anything, it should be automatic.

Just make sure the vehicle is not in a closed space like a garage and you have the engine running. Start the car and leave it for a minute for everything to initialise, then try the update. The licence is verified OTA via the telematic unit's own connection to PSA servers..

Dear Marc,

Thank you a million for the help. In the end, I managed to update via the Citroen app and the main problem was my Mac computer:) When I prepared the USB via the Citroen app on Windows it installed both Software and Maps smotlhy. Currently, I have software version 42.03.33.42_NAC-r0 and map version 10.0 (Which is a significant improvementl since the map version was 6.0 ). My VIN Number is VR7**************[VIN obfuscated, can be read by forum staff].

I have a few questions for you.

For my VIN number VR7**************[VIN obfuscated, can be read by forum staff] is this the latest version of official software available and maps?
Why Citroen app (computer app) show me again to update it to the same system (42.03.33.42_NAC-r0 and maps). I presumed that it should register the new updates and that it would show that no updates are available?
Can I update just maps without further updating of the firmware and if yes can you send me latest available maps for my system?

Sorry for such a long message.
