these inside

Oh ! I see.
Maybe I place voice folder at wrong place. (Because I offen to flash modified firmware and I need to delete voice folder)
But at lease now I know we can place voice folder in root directory in internal memmory. :) :)

I have in root too,with all the voices, now wondering for what these in system are for? May be created by Oxford language guide?

Which folder can we delete from .system ? (and nuvi can still run :: without function from that deleted folder)
The answer is
ASR
Diag
FCD
G2S
GPS
JCV
Voice
Logs
Sqlite
Trips
All of maps
.gcd file
all of .sum files.

!!! :) :)

GPS.,FCD.,Diag.,Sqlite ==> you can try to delete and you will find it appear in .system again when you re-boot nuvi.
(Nuvi will "write" these folder not read from.)

When you delete Text folder :: nuvi will use default Text (American Eng.)
When you delete Keyboard folder :: Nuvi will use default keyboard (American ENG.)

It seems nothing is big deal !! :) :)
So it's reason why we can formatt NUvi (FAT32.) then we have nothing inside Nuvi anymore but we can put everything back to wake it up again. :) :)
