You have 3 mapping options for add-ons to Dashboards. Centigon as you already saw, a newer offering from Data Saavy: http://www.datasavvymaps.com/datasavvymaps-introducing/
You will see 5 or so blog posts about all the functionality you can gain with those maps.
The 3rd option is Galigeo which also offers ESRI integration.
