Can you imagine.?? when I tried to find points of Interest near Yosemite. It said No POI found ..Garmin has Mapsource that is far better than Navteq.It has the options to create automatic, point-to-point routes on your PC without need of a GPS so that you can create multiple waypoints, routes before your transfer it to your device.
Negative
