The system will see it on the NMEA2000 network. I have not seen a method of interfacing like the ZipWake manual states that you can. What I have noticed though is that I have to turn on my ZipWake controller before turning on my NMEA network or the controller will not power up properly, but it will use my SCX-20 as it's GPS source. That is the only reason I have kept it on the NMEA network.
