Yo los pagué; tiene más funcionalidades, la versión gratis es para probarla y poco mas;
- The Shareware/Demo version is missing many features that you get in the full purchased version click here for details
- But it does allow full communication with the GPS for upload/download and moving map
- Only allows maps in BMP image format to be loaded
- Only loads maps in WGS84 datum
- The Trial Version has almost all the features of the full version (works with all supported image formats and datums) but with these limitations
- No communication with the GPS for upload/download
- No saving or loading of Waypoints, Events, Tracks etc
- No saving of map as an image file
- Will close down after 1 hour of running (must be restarted)
