I am aware of this. It is one area in which my simple library could be improved! Jukka wrote: "I believe that for OpenJUMP a better approach would be to use standard NMEA sentenses and stream them to OpenJUMP for further processing." This is an intersting use case, but not one that I am interested in pursuing at this time. It would require that you have a laptop or other mobile device capable of recording a NMEA sentence in real-time while collecting data in the field, and this isn't practical for my applications. It might be better to read the NMEA format from the Garmin instead of the proprietary format. I will need to look into this. Thank you for the comments.
