MANAGING GPS NAVIGATION
Route planning has come a long way from paper charts and slide rules. If you like to plan trips down to the smallest detail, then the free Garmin BaseCamp software might be of interest. Although the software does more than just help plan routes, it also displays topographical maps, allows routes and waypoints to be entered, photos to be geotagged and, through the Garmin Adventures site, can display your journeys to family and friends. No bad for free software - obviously goes best with a Garmin GPS unit.
