How can i use maps

Hi there,im new… i cant find a manual to lear how to use maps in suitecrm
Someone could explain me how can i do .
is it possible do routes ,gps tracking ?
When i create a marker after that i reopen the map but the system show a default map as state .i’d like the default will be a zoom on my markers not zoom on country of my markers…

Thanks,
Stefano
