Our autopilot is chronically losing GPS steering functionality. In the picture below you'll note "GPS steering" is not an option as described in the manual.
This has happened a couple times now and the only way I've found to fix it was to go through the calibration all over again. Any idea why this keeps happening or what I'm doing wrong? Any help would be much appreciated. I hope people have been enjoying winter boating as much as we have this year.
