Map update failing (14.0.0...

Hi again! After firmware upload everything is okay and working. Thanks for your comments and advices.

No problem, well done.

@Juan Sheet what do you mean by doing your updates manually , I have all the updates downloaded onto a brand new USB but haven't had the confidence to load them onto the car in fear of totally messing it up . Also the need to have the engine running the whole time is a pain. I did think about doing it on a long journey but if you stall the car what are the consequences .

I'm not sure which post you're referring to (would help if you quoted the relevant post), as what I say needs to be taken in context of the specific post I was answering.

However I assume you may be referring to the Citroen App for your updates.... This being the case, if you've read any of the posts on this thread you'll be aware that the App is pretty much useless 90% of the time, with updates failing constantly, which is why people are reaching out for the manual updates.

This basically means I can often provide the direct links to the map or firmware updates and owners can install these at their leisure without the need for the app, as long as they have some basic computer skill (extract files using a compression utility, formatting a USB correctly and copying files etc.)

The other issue that affects a lot of people is that on some versions of the Connected Navigation units, they did start using combined firmware and map updates rolled into one update package and that has been pretty much a disaster for most people.

It is essential to have the vehicle's engine running as these updates can take 45 minutes or longer depending on system, the map update or firmware size for example. If you do not have the engine running, the vehicle's energy management system will kick in and put the vehicle into economy mode and this will mean removing power from the Head unit. IF you are updating the system when this happens, you can in the worst cases brick your Head Unit. Never attempt an update unless you have the patience and the time to do it.

If using the vehicle while performing an update, be aware that you will lose access to some controls like the climate system and other features - so don't fiddle with controls whilst doing this. Also, deactivate Stop & Start for the journey and don't switch the ignition off during the upodate.

Hi everyone.
Dose anyone have a link for the newest update 44.07.33.32_NAC-r0? I was able only to download the Cartography 16.0.0-r0.

You may want to ask Here as further details will be required.

On the MyCitroen app, provided you have entered your cars VIN and you click on the car symbol at the right hand side it will bring up car details and under that Touchscreen and map updates.
If you click on touchscreen it will open a page on which you can send the link in an email.

It doesn't anymore send you the link directly for the Citroen PSA server as it did before.

Hello everyone,
expirienced the same issue during map update on me Citroen e-C4 and tried to find information everywhere. I was able to solve "map-eur update had failed" issue and would like to share some steps. All operations I did on MacOS (Macbook).

Following actions requires basic linux user knowledge base:
1. Format the USB drive properly (FAT32) via Disk Util (OOTB application).
2. Get the maps package
2.1. Maps can be automatically uploaded to the USB Disk via official application (Citroen Update).
2.2. Somebody can share you maps package and simple copy-paste to the USB Drive.
3. Validate that USB Drive have following folder structure:
SWL
--> {00231some_digits_there350505}
----> Certificates
----> Data
----> HashList.ini
----> MediaHeader
4. Open the terminal (console)
4.1 Proceed to your USB drive folder, for my case it's "KOSMOS32":

CODE: Select all

cd /Volumes/KOSMOS32

. To get the list of available Volumes type

CODE: Select all

ls -ltr /Volumes

4.2 In the every folder on your USB drive remove MacOS generated files, like .DS_Store, ._.DS_Store, ._HashList.ini, etc.
4.3 To find all MacOS generated hidden files, use command:

CODE: Select all

ls -lah

4.4 After that, you will see the list of existing files directories and hidden one (starting with dot ".").
4.5. To remove all files started with dot (".") you can use following command:

CODE: Select all

rm .*

5. Example! I'm already removed all MacOS fils in first and second directories and would like to validate the list of hidden files in the directory

CODE: Select all

/Volumes/KOSMOS32/SWL/00231{some_digits}0505/Certificates

My algorithm:

CODE: Select all

ls -lah
(base) ➜  Certificates ls -lah
total 256
drwx------  1 user  staff    16K Sep 29 16:21 .
drwx------  1 user  staff    16K Sep 29 16:48 ..
-rwx------  1 user  staff   4.0K Sep 29 16:21 ._PSA-OVIP-CS-G1.crl
-rwx------  1 user  staff   4.0K Sep 29 16:21 ._PSA-OVIP-CS-G1.crt
-rwx------  1 user  staff   4.0K Sep 29 16:21 ._PSA-OVIP-G1.crl
-rwx------@ 1 user  staff   860B Sep 29 16:21 PSA-OVIP-CS-G1.crl
-rwx------@ 1 user  staff   2.8K Sep 29 16:21 PSA-OVIP-CS-G1.crt
-rwx------@ 1 user  staff   889B Sep 29 16:21 PSA-OVIP-G1.crl
(base) ➜  Certificates rm .*
(base) ➜  Certificates ls -lah
total 160
drwx------  1 user  staff    16K Sep 29 16:49 .
drwx------  1 user  staff    16K Sep 29 16:48 ..
-rwx------  1 user  staff   860B Sep 29 16:21 PSA-OVIP-CS-G1.crl
-rwx------  1 user  staff   2.8K Sep 29 16:21 PSA-OVIP-CS-G1.crt
-rwx------  1 user 8-)   staff   889B Sep 29 16:21 PSA-OVIP-G1.crl

As you can see, as result all files started with dot was removed. I had to do this operation in every folder. For the folder ".fseventsd" in the USB Drive root directory I had to use command "rm -r .fseventsd". Also there is another directory in the root folder called ".Spotlight-V100", but MacOS doesn't allow me to remove one. All good there.

Also to eject your USB Drive properly I recommend to use Disk Utility or CLI command:
1. Check all Volumes: "diskutil list"

CODE: Select all

(base) ➜  /Volumes diskutil list
/dev/disk0 (internal, physical):
# nothing interesting there
/dev/disk3 (synthesized):
# some virtual disk
/dev/disk4 (external, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     FDisk_partition_scheme                        *31.0 GB    disk4
   1:     DOS_FAT_32 KOSMO32                 31.0 GB    disk4s1

2. Eject USB Drive: "diskutil eject /dev/disk4"

CODE: Select all

(base) ➜  /Volumes diskutil eject /dev/disk4
Disk /dev/disk4 ejected

Hi there, I've spent over 1 month trying to update maps on my C5 Aircross. Interestingly, firmware has updated smoothly but maps got stuck in the "map update error". Tried all possible ways of formatting USB stick (including crazy 7-pass formatting that takes few hours to complete), different download methods (manual & via the Citroen update app). Also different USB sticks, memory cards, you name it. Here's the problem - I was using a Mac computer for all this, same as Bodyanuk in the post above. It's misleading as the official Citroen app runs on Mac, but is clearly not capable of producing a working USB drive...

So this is what worked for me -> as I didn't have a PC, and am not that techy to delve into command line tools, I've downloaded TAR files from this site https://sites.google.com/view/nac-rcc/system/nac/wave-4 directly to my Android phone where I could extract them using a free FileManager+ app and then put files on the USB drive. Voila! It worked flawlessly. Lesson learned!
