Last trip out I logged a lot of sonar between console and bow units. The console unit logged the recognizable sonar logs and I've uploaded them. The bow unit, I logged "GSD" files which I don't know how to upload, or Navionics won't upload. These are sonarchartlive files? Can I do anything with these files??? I didn't change any settings when switching to the bow unit. It would be better for me if I logged everything to one card, the console card, but not sure if that is doable from the bow unit while fishing????
