You provide very little detail, but from what I can tell is you have a NASA AIS receiver connected to the Keyspan adapter. You have the Garmin GPS connected to the NASA AIS receiver.
In that configuration you would want to set GPSNavX or MacENC this way
GPS panel Settings drawer - Port: /dev/cu.KeySerial1, Rate: 38400, Type: Other
AIS panel Settings drawer - Check "Use GPS Port", otherwise you will get the error port cannot be opened because the GPS panel is all ready using that port.
We do not recommend running the GPS receiver through the NASA AIS receiver because it only passes one NMEA data sentence through ($GPGLL) so you will not get active waypoint, satellite, routes, etc from the Garmin.
Instead we recommend using two Keyspan adapters, one for the GPS and one for the AIS receiver and choosing their respective ports/rates in their Settings drawers or using a Multiplexer such as the ShipModul Miniplex-Lite and configuring as described at the top of this post.
