When i add a map to that page in admin (wp-admin/page.php?action=edit&post=843&message=1) i click on - (minus) till maximum view (the whole planet).
save the page.
and in result it has a maximum zoom (when we see houses).
so i click almost minimum to stay it as i choose.
Tell me please - how to zoom it at minimum level?
