I have a new 06 expedition with nav.
Recently when I hit the "map" button... The display (vehicle) arrow moves over the road way too fast and ends up showing me up to 1/2 to 3/4 of a mile ahead of where I'm at.
I try to make the vehicle position adjustment through the nav menu but it will eventually go right back to being out of whack.....
Is there any solution for this before I take it to the dealer?
