Marine Mode: Navigation
You can choose either time or distance as the method for controlling navigation leg transition.
1. From the Home screen, touch
2. Touch an option:
• Turn Transition Time—set the time, before a turn in a route, at which you transition to the next leg.
• Turn Transition Distance—set the distance, before a turn in a route, at which you transition to the next leg.
• Off—transition when you arrive at the next leg.
Increasing time or distance can improve autopilot accuracy when navigating a route or an automatic-guidance line with many frequent
turns, or when traveling at higher speeds.
Decreasing time or distance can improve autopilot accuracy when navigating a straighter route or an automatic-guidance line, or when
traveling at slower speeds.
