The Vietnam Openmap is based on OSM data covering whole Vietnam. It is ideal for any outdoor activities but also usable in urban areas.
The OSM data has been compiled to a single Garmin mapfile which will be placed on the GPS unit itself. Just copy - easy to use.
The price for containering the OSM data is 9 USD. This map file can be used on any Garmin GPS unit. No unlocking necessary.
