along the route, where you are now, or near another place. Of course, POIs change, so you’ll want to frequently download and install a new POI database from the GPS manufacturer, especially before a major road trip.

USING A STREET GPS TO FIND A TRAIlHEAD
Since trailheads are rarely found in POI databases, you will probably have to enter coordinates. You can get the coordinates from a printed map, but the easiest way is to locate the trailhead on a digital map. Just point to the trailhead location with the mouse and read the coordinates from the display. Be very careful as you manually enter the coordinates into the street GPS—cross-check that you’ve entered the correct numbers several times. A typo could take you to a place miles from the trailhead. Then save the location as a favorite, using a name that describes the trailhead. Now you can pick the trailhead from your favorites list and navigate directly to it.
On the way to the trailhead using a street Personal GPS, the display shows a turn from the highway onto a dirt national forest road coming up on the right in 7.5 miles. The road name, Hart, is misspelled in the GPS database. This trailhead was manually entered using coordinates taken from a USGS topo map, and can now be selected like any other POI. This street GPS shows the route’s distance, time, and fuel cost.
