you approach you destination point.

     Map Colors— Water /Land Mode or For Shade/Sunlight (color models only): when in “Water Mode”, 

land will appear as a darker color and water will be lighter. In “Land Mode”, land will appear as a lighter 
color and water will be darker. If using optional BlueChart data, it is recommended to use ‘Water Mode’. 
For color models, “For Shade” is designed to match the color of physical marine charts as closely as 
possible. Use this setting when in shaded environments. “For Sunlight” displays more vibrant colors for 
use in sunny environments. BlueChart data may be used with either color model mode.
