2011 SD Navigation System?
I have decided to buy a 2011 F-350, but I'm not sure how good, accurate and reliable the Ford navigation system (packaged in Lariat Ultimate and King Ranch) is. I have a Lexus LS and an Acura MDX with great Nav systems, but how accurate and reliable is the Ford system? Should I consider extended warranty on the system? I would welcome comments from current owners. Thank you! Jon
