Hi all.

I bought an NBT retrofit from Bimmer retrofit 4 years ago, im having some issues that i really want to get fixed.
1st issue is language going back to Deutsche, not a bil deal but annoying since i don't speak it.
2nd and this is only happening with my other key sound level and audio source resets, and language.
Im not sure why there is a different with keys.
Bimmer retrofit is telling me i need new software however it was updatet by BMW a year before i got the retrofit so it was at E060-12-11-500 and i updatet it to 14-11-500
I have VO coded 609 and production date 09\09, i even tried 03\10 but problem it still there.
Also tried FDL coding NBT unit setting master language to english_UK and IBA to nicht_aktiv
Anyone out there have any ideas? I was wondering if i should try to flash the NBT but im not sure if i will loose any functions?

Istep or VO coding of the car in E60 has no relationship to a NBT retrofit
If you are having issues, either emulator firmware or FDL coding of the NBT.
