I am really hoping I did not screw up when I bought this unit. It's hooked up and the transducer is connected. I've got power but really am having a hard time understanding the advantages of this system. I get the draw your own concept whikle on the water but with the activecaptain can I go to that app, locate a map and use it on this unit? Can that map be downloaded to this unit through wifi, or will the unit recognize the lake I'm on when I get there as with Lowrance. Can I view a lake while at my home through the unit as I can through the aptivecaptain site on my computer? Yes - a lot of cans but I think this has potential once I get the hang of it. THX
