S1/8002 Not holding Course

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Travis,

If after sea trialing the autopilot to establish its sensed deviation and then aligning the compass, should the heading reported by the autopilot differ significantly (as you have reported) from the vessel's fluid filled and properly calibrated compass, then it is possible that the autopilot's fluxgate compass may be failing. Please click here to view a FAQ addressing how to test the autopilot's fluxgate compass.

Regarding the steering symptom, what model of autopilot drive unit is installed onboard?
