Furuno 511 サービスマニュアル

3. STEERING MODE 

AUTO mode will maintain a set course, but your vessel’s course may be shifted 
by the effects of current or wind. ADVANCED AUTO mode maintains a set 
course while compensating for the effects of wind and tide. Note that your 
NAVpilot-511/520 must be connected to a (GPS) which outputs own ship’s 
position data (L/L) in NMEA0183 format to the NAVpilot-511/520. 
 
In the ADVANCED AUTO mode, the NAVpilot-511/520 will calculate your course 
based on your present position and heading, and by setting a virtual “waypoint” 
in its memory to navigate towards. If either tide or wind begins to push you off 
course, the NAVpilot-511/520’s processor will correct your heading accordingly. 
In this mode, “AUTO” appears on the display.
