8.1. Mapping introductions
Before NSG version 1.4, it can only provide OSM (open street map) mapping method for users. But OSM is not working very well in China because of different standards in location definitions. So NSG introduces China Mapping components in version 1.4. Chinese users can enable this feature in settings menu. Please restart NSG after this option is taken effects. In other regions, OSM is working well and it is not necessary to change this option.
