I believe you can upload a map from Mapquest, if you have sync services set up as well as a phone set up with your FiST. I used this a few times, but it was easier to input a destination, and let the GPS unit figure it out. To use mapquest, you have to enroll at the Ford website for sync services, then add an app, I believe, then get your route through mapquest, then send to your phone, gets uploaded to your nav unit, and you are set.
