ok I have two solix 10 mega + g3 units. there is an update 3.980 that had came out and i never updated it. Hummingbrd says I can do that update without doing the 3.500 update on the G3. But the question is will I have to first do the 3.980 before the upcoming ypdate with mega live data? Also will i lose all my saved way points in doing update? Thanks team..
