So from that the outgoing connection is working, therefore baudrate and outbound serial connection is working - the incoming connection is on the same page so there are only a few variables to play with. I am not at the boat but will screen shot it next time I am
Oh awesome! So you do have it working! When you get back to the boat, check the Garmin settings and make sure it's sending nmea0183 data. I'm not familiar with Garmin, but I'd guess there's a setting in the unit to "turn on" the connection.
