Interesting article...if anyone can get to the bottom of it, you're nominated! Doesn't matter much for me as mine was an Sept build 07 and didn't have NAV. Regardless, I traded her away last month and now I have it all on the new Focus Titanium, MyFordTouch, Sync, Nav, etc. Amazing how a $25k compact comes packed with all the technology and the $40+k Expys back then didn't get it even thought the technology was there. Always seemed strange to me.
