ok well I've tried the Navteq version with the associated ASR files and the voice command for 'Find Address' etc... still does not work.
So I'm coming to the conclusion, based on the table above, that there are additional ASR2 files missing/not available in the AU/NZ 2013.10 map version for the 34xx/35xx nuvi series.
I guess we'll just have to wait for the next version to see.
