[CA] [CA11] Evolution autopilot track mode

[Fender]

Hello,
Newly installed evolution autopilot connected to axiom pro 12 MFD.
Autopilot works flawlessly in auto holding a course, whether at idle or at 50mph.
When a spot is chosen and pilot is commanded to "goto" it will golf course but constantly steers 30° back and forth.
My question is...... Is this just a simple setting that I need to adjust?
Thank you for any help.
More info..... Evolution 150, hydraulic steering, 26' grady white with twin outboards.

Welcome to the Raymarine Forum Fender,

Please update the ACU with the v3.12 software update released earlier this week. After doing so, then it would be recommended that the actions specified within the FAQ found here be executed. Should the problem persist thereafter, then please indicate the maximum sensed deviation value when the vessel was taken out for the cruise to detect magnetics. Please additionally indicate whether you installed a rudder reference transducer.
