Big diff between a true GPS setup and something like Map Quest. Almost all GPS foul-us are the operator.
Map quest sucks! Had an job interview at a hospital about 30 miles from my home. Got directions off of map quest and did a trial run the day before the meeting. Followed the instructions almost to the end and then it tells me to go straight at a 4 way intersection and the destination was 1/2 a mile ahead. Only problem was that the intersection was only a 3 way and straight would have put me into Long Island Sound! They were right tho, I could see the hospital across the harbor! Have never used it again!
