Evolution ACU-200 Incorrect Response During "Track" mode

[chartertom]

This thread relates to my ACU-200 that incorrectly responds when operated in "Track" mode. When the autopilot was set to "Track" mode to navigate towards a selected waypoint that was approximately 10 nm fro current position, the autopilot steered the vessel 180 degrees from the destination waypoint, traveled approximately 0.25 nm, and signaled waypoint arrival. A second that third attempt yielded the same result.

It should be noted this autopilot performs perfectly when operated in "Auto" mode, but has not been tested in any pattern modes.
