Firmware change

Hi all,

I am an Australian currently living in Thailand.. recently I purchased the Approach S62 however the version is Approach S62 Asia.  I understand this has to do with language support.  As I am a native English speaker is there a way to update to firmware to either the Australian or US model so that I may get the updates faster, please.  The non-English speaking devices lag significantly with updates and I'm having notification issues, aka, I'm not getting them..  I'm running Golf 2.01 which I had to manually update for some reason 

Thank you
