When picking up any new car you should make sure as much as you can, that what you paid for is what you get. Me, I would make sure the dealer installed everyhing required for the sat nav as I am pretty sure if you say you had a go and it still don't work, Ford would be saying it was something you did. Only thing I and quite a few others had, was the glovebox out of shape, dealer swapped it for a new one no problem.
