Google Maps pull from spreadsheet

I have just installed the Google Maps plugin to see if it will do what I need it to do. When I go the Settings page I see no options and there is no icon to add a map to the page.

If I can get it fixed - can you help me know if it will do what I want?
I have a couple of google spreadsheets with data that needs to be linked to create an interactive map like this - http://www.greenwaysfornashville.org/maps-trails/interactive-map. I am recreating this site in wordpress for the administrators to have easy access to edit.

I can send users offsite to connect to these maps but would prefer to keep them in one site if possible.

Thank you.
