Navigation System Updates
 

Can someone help to figure out what the latest updates are for the maps display and the points of interest in the 2009 Escape? How often are they updated?

I purchased my vehicle 15 May 2009, and I want to be sure that I was given the latest software release as of that time.

I would also like to find out what the cost of the latest upgrade is.

Any help here would be greatly appreciated....!
