Hi, my newby question is about my brand new, not even overboard yet 899SI. Seems when I power off and watch countdown then screen say's "Humminbird is powering down" it,s just pretending and will hold that screen for, well I guess till the battery is dead or I cut the power. Anybody having like trouble? Do you think this might be a software update fix or do I need to get the packing paper out. Standin By thanks, BB
