I finally got my LCX113c hd hooked and powered up at home on Monday. Map showed exactly where I was at. Went fishing yesterday, powered up the unit and GPS map showed my home location. I scrolled to where I was fishing, zoomed in and fished the day. Turned the unit off when I dropped anchor, fished then when leaving I turned the unit on which displayed my home location
. How do I set the unit to display my actual location each time I turn the unit on?
