PSA NAC RCC Updates

[Dexter676]

Hello
Maj friendy
I've succesfully updated firmware on my citroen berlingo 2018 from WAVE 3 to wave 4 using firmware downloaded via citroen update program on windows pc. When IT asked to.choose firmware and maps I online choose firmware now I Will try only maps. Bofere that i've tried both at the same time in one download firmware and maps(its also recomended in instruction to do IT that way) and get well known message that IT is Not compatibile with hardware. So maybe they fixed certificates already and IT will work for Everyone or maybe, we Just need to do separately fort firmware the maps.

And maps are also working. So i Think they fixed issue with certificates of update from WAVE 3 to wave 4.or we need to instal firmware first separately.
Few months ago i lost hope in citroen /PSA i thought they Just dont give (-expletive removed-) about that couse warranty already expired. But now love is back.

Hello,
Good news for you.

Your updated firmware was 43.03.33.42_NAC-r0 or 44.07.05.22_NAC-r0 ?

[Dexter676]

It get updated to 44.07.33.32_NAC-r0

Before you were in 31.09.46.62 ?

And Did you need to use a license file ?

[Dexter676]

Before it was 31.08.05.86_NAC-r0.
For sure there was license key on pensrive as i mentioned before i used original program citroen update to make a update pendrive for my berlingo.

and what message was displayed on Citroen Update before the update : one of these ?

[Dexter676]

I was able to pick both but I only choose firmware, and prepared one pendrive, then open program again and prepared second pendrive with only choosed maps. And in car first I put pendrive with firmware only and after succesful update I put second one witb maps

So IT was like in screen 3 but in polish or English. (I'M from poland) before that few months ago when i got message that its not compatibile with hardware i contact citroen polska, through e-mail but in response they send me the same files that i was able to download through citroen update which didnt work, then told me to go.to nearest authorized service. Which i didnt do couse i dont have time for that, and read on some forums that it didnt work also Just waste of time.

Hello I'm a little lost with this as theres so much info in this post, and Im dyslexic,

I have 2020 C5 aircross
firmware showing as 31.09.46.62_NAC-r0 (I don't think its ever been updated)
My car has WIFI

ive tried the app and it will only download maps v17 no firmware update even though its old ,install fails to update
I believe I need to do firmware first ? but lost on which one or how many I need to do or if I need a licence or not
if someone could help me with which firmware I need please, do i need to do loads of updates to catch up..

thanks

Good evening,

For the moment, there is no certainty, but if when we are on 31.09.46.62_NAC-r0, the update offers the V17 map, it seems possible to install directly the version version_44-07-33-32_NAC-r0_NAC_EUR_WAVE4.
However, you need to find the corresponding license file, which is possible with the link:https://majestic-web.mpsa.com/mjf00-web ... UUUUUUUUUU

by replacing UUUUUUUUU with your NAC's UIN.

What if im wifi my car has built in wifi.

how do i find the uin please
