hi guys.

I wonder if I can change my language of my MK2 Nav computer BMW E39.
I recently did the V25 software update.
for me its only possible to choose D (german female) and GB (english Female)

i would like to add or replace one of the two option to NL (dutch female).

I tried to rewrite the official V25 firmware to make this possible. but de cdrom wasn't accepted.

when I look in the official FW I can see more languages like Italian french etc except NL(Dutch).
but it does not show in the menu.
I heard there is a possebility to have this changed to NL menu and NL voiceguide (female.)

Who knows if its possible to make this change, 2 languages but not in my own language on this Navigation is a poor kind of navigation in this expensive outfit,

who can help?
