Does anyone use Maps in their sonar/GPS? I have a Lowrance elite-5 and thinking about getting map software for it. What does the Lowrance Insight Maps have on it? I have an older Garmin GPS unit that I had purchased the hotspots maps for. I like that it tells you the fishing spots on lakes... Not just contours. I'm not looking at Navionics because they break their Maps in to regions that I would have to buy 2 regions in order to get both Illinois and Wisconsin.
