Haven't done the upgrade, but I can tell you the new Nav system info is merely an SD memory card (like you would put in your digital camera) that plugs in a port located inside the console.
The old system in my 2009 was an actual hard drive, which has been eliminated from the lineup, which is probably why the Nav option went from a $2300 package to $800.
Couldn't tell you if the maps are better or worse, both my wife and I have used it on occasion, but it's probably the newer revision.
I prefer to have the dealer install upgrades like that, so that if anything goes sideways, it's tough to put responsibility on me when it was Ford software installed by Ford techs..
Much like a lot of other things, comes down to your personal preference.
