Display Chart Overlays

If you purchased a Humminbird LakeMaster PLUS map card or ChartSelect lake maps (that are saved to an ecrypted SD card), you
can select a base layer and add overlays to the Chart View to add more detail to your map.
The available settings are determined by the installed map card and selected map source. The LakeMaster map card or SD card
