Road Positions Appear to Be Inaccurate on the TOPO U.S. 100K Map
TOPO U.S. 100K roads are based off of data which may be slightly off depending on a user’s location. Not all roads will display in error. Geographical points of interest such as streams, contour lines, etc. will display accurately.
If more accurate road detail is required, choose from one of Garmin's City Navigator® NT mapping programs. This software is intended for detailed road navigation and can provide more accuracy.
