updated my Helix 10 G2 Mega SI on Saturday, 9/30. Update went fine, software load indicated on self test screen. All the new changes were installed. Fished a tournament the next day, expecting the the 2d to work better and had the same issues of the depth reading jumping all around. Left everything on default to start the day, then tried to adjust things like Max depth, and depth source, but was unable to correct it. Took some screen shots of the depth readings, tried to upload but file was to large, anyway depth read 540 ft, 1077 ft, etc. Anybody else have trouble with the update? Not sure what I did wrong. Any ideas? Thanks.
