I input my addresses that I want to go to and it directs me there just fine, the problem is when I get there I am usually 5 to 6 houses from where I should be. It the same with business destinations. It just seems to be a good 500 or 600 yards off. All my setting are fine, my speedomter on the d3 is perfect and it tells me to turn when i need to turn. If I am aproaching a turn it will tell me a turn is coming up in .5 miles, and It is exactly .5 miles away. When I look at the map, I am right where I should be. Is this just something I am going to have to live with, or is something wrong
