To use the Spot tracking mode that you pay Spot $50 a year for you must set up a public shared page on the Spot website. When you set up the page, make a note of the last part of the URL after "glId=" (copy and paste). Edit your database entry on this site, adding 33 character string from the URL to the "shared page" field. Once you have that your database entry should show a link to the shared page, and a link to the XML data that is used to generate the map. If they work, you should be able to enable your Spot for tracking.
When you enable polling for track data it stays on for 12 hours, then resets. Currently you can't turn it off.
Polling occurs every 15 minutes, and data may be delayed. You get much better performance using 'Help' mode.
