Beware of Ford Lincoln Navigation system - It appears that most of the vehicles are delivered with OUTDATED AND OBSOLETE NAVIGATION DVD'S - DVDs are assigned as the vehicle is built - and you more than likely will get an outdated Nav DVD - Be sure to verify the latest available version BEFORE YOU BUY - FORD DOES NOT INCLUDE THIS IN ITS WARRANTY NOR WILL THEY PROVIDE THE DVD WHICH SHOULD MATCH THE YEAR OF VEHICLE. BUYER BEWARE - FORD'S INTEGRITY IS LACKING IN THIS AREA.
