Can anyone help me, my 798 si keeps locking up. it loses gps signal and the power button doesnt work. I have to remove it from the base to shut it off. I do have 3 batteries in my boat all isolated (starting, trolling, everything else) My gen 1 helix 7 seams to work without issue wired to same battery.
also why does this unit want to read echo reading. last trip out it was reading 300+ fow when we were only in 10 fow. it kept zooming out on me. is there an update for this model and where can I get it? I had registered this unit on my account with humminbird but now I cant get logged back into my account
