H-bird 899 won't turn off/on
Got home from fission a week or so ago and noticed after charging my batteries that my rear fishfinder a hummingbird 899 was on the start up screen. I pressed the button to turn it off it said shutting down and said that for 20 to 40 seconds or more. I disconnected the power away from it and went it. Next time I fished I noticed it would not go off at the ramp when loading. Disconnected power again. It's under warranty and I have read about voltage. No nic's or corrosion that I see. Hoping someone has info in this before I take it back to marina who installed.
