autopiolt steers in a circle

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Nick,

It is recommended that the autopilot's fluxgate compass be tested and that it's rudder reference transducer be tested. Should the devices pass testing and should right and left steering commands cause the vessel's rudder to move in the correct direction, then it would be recommended that the autopilot's course computer be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
