The map coverage varies by country.
When you open the
Maps
application,
Maps
zooms in to
the location that was saved from your last session. If no 
position was saved from the last session, the 
Maps
application zooms in to the capital city of the country you 
are in, based on the information the device receives from 
the cellular network. At the same time, the map of the 
location is downloaded, if it has not been downloaded 
during previous sessions.
