Will I need a plug adaptor to use the AC adapter in Australia?
Does the AC adapter come with a UK plug on it? If so I guess I'll need a plug adapter to fit Australian sockets.
But it can also be charged through the USB from a computer right?
I just use my iPhone charger and the garmin cable (USB to mini USB) or let it charge when attached to the computer when doing uploads. This may save you buying an adapter.
