First time on the water with 3.00 upgrade in my Onix. the screen locked up twice. once while in Auto Chart Live, trying to get a split screen. and then later when creating a new view with 2d and di. I have checked power connections and battery. it did not do this before the upgrade. I unplugged the unit ,waited 20 seconds then repowered, and the last time did a reset. worked fine the rest of the day. Never lost depth even at 1.7 feet. Auto Chart Live is awesome by the way!
Happy fishing guys
