I'd still be interested in hearing about anyone's experience with such a
hook up.
Most auto pilots want to know cross track error ($GPXTE), course over
ground ($GPVTG) and bearing to mark ($GPBWC).
I read throug the Garmin manual online and can't find any mention of
cross track error. I'd call Garmin tech support.
