Hi All, I'm looking at picking up a 2011 XLT for my wife. There is a demo at local lincon dealer that has 5K on it. It has the myFord touch system, so it had the screen and everything but it doesn't have the nav system. A guy at work told that if you have the myford system all the nav is is a sim card that can bu put in very easily. I was curious if any one if that were true. Before I go in there and ask the dealer, I like to already the answer. Also I know the truck is new and so is this forum, but does anyone know of any nagging problems with these that I shoudl look out for. Any help anyone can give would be a big help.
