Yes, you need to force the nav to also update the new voice files as if its in 0506 then it will not load the files...

You will also need to change its name to the language you will be using to "swap" the language with the one you want so,

if you use eng_f.csf (as alert on) then rename rus_f.csf (mod) to eng_f.csf

If you want the alert on/off option then you also need the file unmodded (off) and modded (on).

So if alert "off" is fre_f.csf, then rename rus_f.csf (no mod) to fre_f.csf

Correct, export the file you want then edit each string and then save then import back to navboot

ONLY If you want alert on/off then you need to change 2 languages, other wise you 1.

Yes, export a language, then mod it, then import, then save navboot.
