Overlay Numbers—control how charting numbers appear on the screen. Choose to show or hide
the numbers by category. Touch Auto to show navigation, shing, and sailing numbers. When set to
Auto, the overlay numbers appear only when that category is active.
Cruising: GPS position, GPS heading, GPS speed, and depth. Depth is only available if
connected to a sonar unit (page 48).
Navigation: GPS position, distance, arrival (time), bearing (to destination), GPS heading, and
GPS speed. These numbers appear only when navigating to a destination (page 21).
Fishing: GPS position, depth, water temp, and water speed. Depth, temp, and speed are only
available when connected to a sonar unit (page 48).
Sailing:
GPS position, waypoint velocity made good (VMG), wind speed, wind direction,
water speed, and depth. Wind speed and direction are only available when connected to a
NMEA 0183 wind sensor. Water speed and depth are only available when connected to a
sonar unit. If you have a wind sensor, setting the sailing overlay numbers to Auto places an
indicator around the boat icon on the navigation chart to represent wind speed and direction.
