I've gotten several different answers on this question. Does the Helix G4N models save all settings when you plug it into a power source at home without a transducer connected and use simulator mode. I want to reset my unit and start again but do it before i get on the lake. I realize that some settings will need to be tweaked after I'm on the lake but wanted to save the majority from when I'm home. Some users are saying you can't do this with the G4N models. Anybody have comments?
