[CA11] Align compass to GPS
For an Evolution autopilot, after performing Align Compass to GPS in flat water with no wind or current, heading, COG, and readings off a reliable compass are all within a degree. As I turn from the original direction where the Align function was performed, the Heading and COG begin to diverge, reaching as much as 8-10 degrees when turned 120 degrees off the original course. The heading is the wrong number as the COG matches the compass. Deviation is 16 and Compass Offset (which was set by the system) was 2 degrees.

What is happening and how do I correct it?
