Firmware 44.07.33.32_NAC-ro

Unread post by Antibabes »

Hi all, i got my 72 plate C4 a week ago. The My Citroen app says there is an update 44.07.33.32_NAC-ro available and maps 17.0.0-r0

I have followed all instructions and only the maps installed. The firmware says it isn't compatible with the hardware.

The car doesn't find an update when connected to my phones WIFI hotspot.

It is currently on 43.04.27.52_NAC-ro

Is it a problem leaving it on the current firmware?

Am i missing some versions prior to the latest preventing the update?

And will i have a similar issue when i get round to attempting an update on a C3 that likes to revert to french? (I'm aware its a seperate download to my C4)

Thanks for any assistance 😀

As you have had the maps update I wouldn't worry about the firmware as long as everything works as you expect :)
I used to be indecisive, now I'm not so sure!

Everything works as it should, so i may just leave it, as long as theres no important things in the update.

If only it was as simple as the C3, that didnt argue at all 😂
