D180 with Garmin GNC 300xl

[mataylor]

I'm wiring my d-180 up and the installation guide says I can hook it into my gps if it outputs aviation format or the NMEA serial stream is a long list of letters. How do I kow if my 300xl puts this out. I can't find it in the garmin manual. thanks

The 300xl is configurable for either I think, but you'll need to get in touch with Garmin for support on what buttons to push to select the output on their products. Perhaps there's a reader here that can give some guidance?

Do you have the Garmin installation manual or just the pilot's guide. The install manual provides details on how to set up the unit including input and outputs. You can find most Garmin manuals at the following site. http://www2.mstewart.net:8080/Downloads/howtogetagarminmanual.htm

Mataylor,

I will soon the undertaking the same process with a D-180 and a Garmin 300xl. I would be interested in hearing about your progress.

Thanks!

I'll be hooking up a GNC 300 XL to a D10a. I just checked my garmin installation manual and you can set IO channel 1 to aviation format or you can set IO channel 2 to NMEA 0183.

The Dynon manual says they expect the GPAPB sentence in the NMEA stream but the Garmin manual doesn't list that as one of the transmitted sentences? The APB sentence is "Autopilot Bearing message". Who knows why the Dynon wants that?

Anyway maybe the only workable setup is to use channel 1 set to Aviation format...

Specifically, one of GPBOD or GPAPB must be present, but you don't need both. If neither are present, the OBS will always indicate 360. This is the sentence we get the course direction from.
