Courses

The Auto Guidance feature is based on electronic chart
information. That data does not ensure obstacle and bottom
clearance. Carefully compare the course to all visual sightings,
and avoid any land, shallow water, or other obstacles that may
be in your path.
When using Go To, a direct course and a corrected course may
pass over land or shallow water. Use visual sightings, and steer
to avoid land, shallow water, and other dangerous objects.
NOTE: Auto Guidance is available with premium charts, in
some areas.
You can set and follow a course to a destination using one of
three methods: Go To, Route To, or Guide To.
Go To: Takes you directly to the destination.
Route To: Creates a route from your location to a destination,
allowing you to add turns along the way.
Guide To: Create a path to a destination using Auto Guidance.

Setting and Following a Direct Course Using Go To

When using Go To, a direct course and a corrected course may
pass over land or shallow water. Use visual sightings, and steer
to avoid land, shallow water, and other dangerous objects.
You can set and follow a direct course from your current
location to a selected destination.

A magenta line appears. In the center of the magenta line is
a thinner purple line that represents the corrected course
from your current location to the destination. The corrected
course is dynamic, and it moves with your boat when you are
off course.

Follow the magenta line, steering to avoid land, shallow
water, and other obstacles.
4 If you are off course, follow the purple line (corrected course)
to go to your destination, or steer back to the magenta line
(direct course).

Setting and Following a Course Using Auto Guidance

The Auto Guidance feature is based on electronic chart
information. That data does not ensure obstacle and bottom
clearance. Carefully compare the course to all visual sightings,
and avoid any land, shallow water, or other obstacles that may
be in your path.

line.

Follow the magenta line, steering to avoid land, shallow
water, and other obstacles.
NOTE: When using Auto Guidance, a gray segment within
any part of the magenta line indicates that Auto Guidance
cannot calculate part of the Auto Guidance line. This is due
to the settings for minimum safe water depth and minimum
safe obstacle height.
