If you’re not already using it, you need to get on it ASAP!
The CMAP Genesis website is very good, it’ll walk you through signing up for an account and how to download the maps. Some lakes have amazing coverage, some are kinda spotty, but it’s FREE. You can even customize the depth shading. If you got to the Lowrance YouTube page, they have some very good videos on there explaining the process as well.
The genesis live mapping is as simple as putting a blank microSD card into your unit, going to your charts menu, and selecting genesis live from the Overlay menu. Drive around and you’re mapping, the more ground you cover and the more thoroughly you cover it, the better your map will be. The genesis live mapping doesn’t share between units, so each unit on the network must be on and have the genesis live overlay option turned on in order to create a map.
