Waypoint not received from Garmin GPS

Hi, I'm trying to transition from MacENC to OpenCPN 5 on my MacBook Air. I can't figure out the following required feature:

My GPS source is a Garmin 180 or 72 at the helm. OpenCPN receives position data just fine. When I do GOTO WAYPOINT on the Garmin, OpenCPN does not seem to do anything with this information.

With MacENC, upon hitting GOTO WAYPOINT on the Garmin, a little window pops up with the waypoint name, distance, XTE, VMG, etc. And MacENC draws the path on the chart. This just happens automatically - never had to configure a thing.

NMEA headers for the active waypoint seem to be GPBOD, GPRTE, GPWPL.

Anybody with a solution for me?

I've also had zero luck sending waypoints to the Garmin 180 from OpenCPN. MacENC sends multiple waypoints at once without flaw.

Cheers,
Andrew

Re: Waypoint not received from Garmin GPS

I use both 128 and 76 with OpenCPN

These threads may help.

Waypoints Uploads OpenCPN to Garmin

Route and waypoint transfer to Garmin 76xx chartplotters

I typically use O for route plotting and then upload to GPS and subsequently goto on the AP. The acquired WP then displays as active on O.

You may need to check "output on this port (for AP or NMEA)" in settings - connections.

There is an issue with early Garmin in way they accept wp / routes.
