6000 miles, had vehicle for 4 months. At least 6 times while using the nav system the vehicle location on the nav system gets stuck on side streets next to the road I am actually on (mostly on freeways) it then takes a long time for it to get to being accurately represented. Had the built in nav on my 2006 lexus that was far superior to the ford 2014. Very disappointed that the technology is not performing.
