Re: PSA NAC RCC Updates
Took the plunge with your information crossed with the wifi method

Re: PSA NAC RCC Updates
Hello, even I tried several times with different type of usb stick, different computers, unfortunately I couldnt manage to update maps on my C5 AC. At the end of my attemps, I decided to check firmware version (even there is no notification on MY Citroen app for firmware update) it is 31.09.46.62_NAC-r0 old version. I think first I need to update firmware (from wave3 to wave4 before maps.

I think you ned to read through this entire thread - yes all 86 pages - to get an overview of this and in particular this post by Rui Saraiva viewtopic.php?p=844359#p844359

Re: PSA NAC RCC Updates
I tried both 42.03.33.42 and 44.07.33.32 with generated licence key file but unfortunately it gives error that the software is not compatible. It should be some way to update it. I ll try 44.02.13.12 as a bridge software

Re: PSA NAC RCC Updates
Update.
I tried also 44.02.13.12 but nothing. Should I continue to try other versions until I find correct one for making bridge between wave3 and wave4?

Re: PSA NAC RCC Updates
There are only two solutions if you're using version 31.09.46.62_NAC-r0.
PSA_update offers:
1) Card + Software 42.03.33.42, but you can't do anything at the moment due to the certificates that expired at the end of 2024.
2) Card V17.0.0.0, and from there, it seems possible to directly install version 44.07.33.32 with a generated license key file.
Nothing else is possible until the certificates for version 42.03.33.42 are revalidated.

Re: PSA NAC RCC Updates
I may have expressed myself poorly.
Only if citroen-update offers map V17 without the firmware, and only in this case.
It is then possible to install firmware 44.07.33.32 first with licence , and only after you can install the map V17 without licence.

Yes, citroen update offers me v17. But I cannot install it. It always give an error.
Let me in detail explain it. I am formatting fat32 usb stick and installing maps EUR (I tried both with generated licence key and via wifi) Then it says found update do you want to continue, I click yes, dont stop engine or remove usb, I click yes. Then it starts to process after 5 secs. I get update is unsuccessful warning.
I also tried to reset system (holding music icon 10 secs) but unfortunately this way is not reseting system on my car.

Re: PSA NAC RCC Updates
you cannot install v17 if you are in 31.09.46.62_NAC-r0.
you must before install 44.07.33.32

Re: PSA NAC RCC Updates
I found that @rui_saraiva said on 05th June :
‘ Currently, it is impossible to install any firmware for the NAC Wave 1 and any firmware or maps for the NAC Wave 3 - all those available files have expired signing certificates. This is something only PSA/Stellantis could fix, by issuing a new certificate and signing the updates with that certificate. This isn't related to the license file you also need to install any firmware.’
Any update about this issue. Anybody knows?
