the path is unsafe, reduce your boat speed and determine a
safe path back to the course.

Browsing for and Navigating to a Saved Waypoint
WARNING
All route and navigation lines displayed on the chartplotter are
only intended to provide general route guidance or to identify
proper channels, and are not intended to be precisely followed.
Always defer to the navaids and conditions on the water when
navigating to avoid groundings or hazards that could result in
vessel damage, personal injury, or death.
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.
Before you can navigate to a waypoint, you must create a
waypoint.
1
Select Info > User Data > Waypoints .
2 Select a waypoint.
3 Select Navigate To .
4
Select an option:
• To navigate directly to the location, select
Go To .
• To create a route to the location, including turns, select
Route To .
• To use Auto Guidance, select Auto Guidance .
5
Review the course indicated by the magenta line.
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.
6
Follow the magenta line, steering to avoid land, shallow
water, and other obstacles.
