This is an odd one and probably a very simple answer, but I am stumped. Situation is OpenCPN
4.0 driving a Furuno
NavPilot 500 autopilot
for route navigation
. AP works fine in Auto mode. This system as worked in NAV all last year and until about mid-July this year. At that point, the AP would throw an "Arrived at Waypoint" alert when any route
is activated. The AP is set to the correct input (from OpenCPN) and OpenCPN
is configed to output for AP on the appropriate com port and with the appropriate NMEA
sentences. Nothing has physically or config changed (that I am able to figure out) with the exception of the replacement of the AIS
receiver with a transponder this year. The NAV function was working with the new transponder for about a month.
I have tried any number of permutations to determine what's up here, but keep hitting a brick wall. Looking for a list of things to try to work down thru, as my list has come up dry. Ideas? Anyone see this type of thing before?
