If you connect the watch to a computer, under the garmin directory is a file called garmindevice.xml. Look in that for "PartNumber". If it's 006-B2700-00, it's the ROW version (Rest Of World) and not the APAC (Asian-Pacific) version. APAC is 006-B2976-00
There's no way to install ROW FW on an APAC device. Do not change the garmindevice.xml file!
i am in Malaysia, my va3 afaik is asian version... and i got v3.40 the day it was released / announced here.
so too for previous firmware updates.
