Hi Chris,

Did you enable maps from Setup -> App Setup -> Customize -> Maps and location -> Setting click on edit and check the "Enable Maps and Location Services (powered by Google)" checkbox and save.

if you org is updated to Spring 15 and you don't have Map and Location option in the setup, you can contact salesforce support, they will enable that for you.

Please let me know if this helps

Best Regards
Naga Kiran
