What will I gain that I don’t already haveIf you are at 2.2 or above the website will allow you and instruct you on doing it via USB. If you are 1.0 (from what Ford told me) you have to go to the dealership to get it done. Or follow some of the threads in here on how to obtain it yourself if you are 1.0. My Expedition came installed with 2.0 and I updated to 2.2 using threads on here and then 3.0 from Ford's website. If you are at 1.0 I would highly recommend getting higher (at least 2.2) Worked great.
