I moved from Lowrance to Humminbird Helix Mega 8SI+. My Lowrance units used to record all my tracks everytime I went out and would be there the next time I went out until I deleted them. My Helix unit does not do that, I lose all my tracks the minute I shut the unit down. Is there some auto track save function I am not using or do I just need to remember to save my tracks everytime I turn the unit off? I am using 2.440 software. Thanks!
