I am really befuddled - I took my 998c out for it's first full day run (after fixing the wiring problem) and it worked GREAT! An amazing system. I've never used a chart plotter nor a SI/DI system before... and I'm really impressed. And, amazingly, it appears that the transducers are set right - at least to my untrained eye.
So, I decided to make a recording of the day's travel and review the chart plot and DI/SI images on my home computer.
But, I've tried loading the recording into HumminbirdPC and can't get the recording to load. The SD card shows about 900 MB of recordings, but after I upload the files nothing shows up in the HumminbirdPC program. I've read the HB manuals on this subject, and reviewed postings on this forum - I just must be missing something really simple (overlooking the obvious?).
Any thoughts about what I'm doing wrong?
