Hi anyone can help me out? I've copy the img to my SD card. I saw the map when I go to map info of my GPS. When I try to change my location (Country) under the address search, there is no Japan found?

I've did the same to "GARMIN Japan Street Map NT v10 (Japanese)" image file and same thing happen. Can see the map installed in my GPS & when I've try to change my country location, I can't find Japan.

I've also installed Singapore map in my GPS and even thou I'm in Australia I am able to change my location (Country) to Singapore but not to Japan.
