[GPSNavX]

Yes you can use GPSGate to be the NMEA data server. Both Coastal Explorer and iNavX can be NMEA data clients. XGate is relatively easy to setup. Basically you select the com port your NMEA talker is connected to (i.e. GPS), then select the ip and port you want GPSGate to transmit the NMEA data to. Set Coastal Explorer and iNavX to listen to that IP addres and port. Email inavx at mac dot com for more assistance with the configuration.
