• If the turns in the Auto Guidance line are too wide, select

Settings >

Preferences > Navigation > Auto Guidance

> Shoreline Distance > Nearest

If you selected

Nearest or Farthest in step 8, review the

placement of the Auto Guidance line, and determine

whether the line safely avoids known obstacles and the turns

enable efficient travel.

Auto Guidance maintains a wide clearance from obstacles in

open water, even if you set the Shoreline Distance setting to

Near or

Nearest. As a result, the chartplotter may not

reposition the Auto Guidance line, unless the destination

selected requires navigation through a narrow waterway.

Repeat steps 3 through 9 at least once more, using a

different destination each time, until you are familiar with the

functionality of the Shoreline Distance setting.
