Waypoint Name (File=>Export=>Magellan eXplorist)
GSAK allows you to generate unique names for your waypoints. The default is to use the "Smart Name" (%smart), but you can use any of the special tags to build a unique name. Use the first field to enter the waypoint name.
If you select Magellan SD format the waypoint name will be restricted to 8 characters. All other formats are restricted to 20 characters.
