Hi, first post here, looks like great info here and I sure appreciate all of the obvious work that went into this! I was referred here to get some software downloads to update my sonars, an 898c si and a 798ci hd si that are both running older software. I downloaded the 6.49 for the 898 and the 6.25 for the 798—however, I was a bit surprised to see the file size was so different on the two downloads (28-ish mb for 6.49 and only 3.9mb for 6.25). I’m a bit paranoid of messing up my sonars, so want to be sure this is correct before I do anything. Can someone confirm that the 6.25 for 798 is actually only a 3.9mb file?
