When you look at the rather lenghty CPO check list, there are all sorts of items that are checked off as to being operation and certified to be in proper working order. The items are either checked as "Passed, Repaired, Replaced, or N/A". On those items the vehicle isn't equipped with, they are checked off as N/A. In light of this being a Ford "Certified Pre-Owned" car, and having Navigation item checked off as passed, would convey the idea that the car was not only equipped with navigation, but that it had been checked and passed.... Wouldn't you think?
