Unfortunately there are no ASR 2.0 files available to download from Garmin for 34xx units in Australia running Aus/NZ Sensis map. Voice command will still function but you will get the dreaded "....feature not available ..." response for some of the FIND commands.
Best solution (if voice command feature is important to you) is to use the Navteq map which has an ASR 2 file available for Aus/NZ Navtech map. This gives COMPLETE voice command function.
Tested and verified on aussi 3790LMT converted to 3490.
