  The route appears as a magenta line, with starting point, destination, and turns indicated.

other obstacles.

The Radar Overlay superimposes radar information on the Navigation chart or the Fishing chart. 

Data appears on the Radar Overlay based on the most recently used radar mode (Cruising, Harbor, 

Offshore, or Sentry), and all settings configurations applied to the Radar Overlay are also applied 

to the last-used radar mode. For example, if you use Harbor mode and then you switch to the Radar 

Overlay, the Radar Overlay would show Harbor mode radar data. If you changed the gain setting 

using the Radar Overlay menu, the gain setting for Harbor mode would change automatically. 
The Radar Overlay does not show data based on the Dual Range radar mode, and settings 

configurations applied to the overlay are not applied to the Dual Range mode.

When using the Radar Overlay, the chartplotter aligns radar data with chart data based on the boat 

heading, which is based by default on data from a magnetic heading sensor connected using a 

NMEA 0183 or NMEA 2000 network. If a heading sensor is not available, the boat heading is based 

on GPS tracking data. 
GPS tracking data indicates the direction in which the boat is moving, not the direction in which 

the boat is pointing. If the boat is drifting backward or sideways due to a current or wind, the Radar 

Overlay may not perfectly align with the chart data. This situation should be avoided by using boat-

heading data from an electronic compass.
If the boat heading is based on data from a magnetic heading sensor or an automatic pilot, the 

heading data could be compromised due to incorrect setup, mechanical malfunction, magnetic 

interference, or other factors. If the heading data is compromised, the Radar Overlay may not align 

perfectly with the chart data.
