I just bought a go 930 going with maps in west Europe and north america.
I tired voice recognition and it worked well.
After that, I tired to use navcore 9.101.516023 with the map [Australia][845.2661][with IQ Routes].
Both of them are downloaded from the link found in forum.
I have ASR folder including files for English language and cspeech_AUS.dat in map folder.
But i could not use voice recognition when address setting.
