May be you are better off without Navigation. I bought Edge SEL with Panoramic vista Roof, Navifation and since the first day, the navigation is not working at all. they said bring it tomorrow and tried to fix and does not work. Now they are telling Ford has accepted that there is some software problem and its on some handfull vehicles and do not have any fix yet. Seems it takes 2 hours to just take out the navigation unit and then dealer has to get some sort of connecting wire to load the software again....
wait until all these bugs are taken care of - Paid $795 for navigation and it does not work.....its a rip off. The hand held units just cost $150 or so and work great...
