Sea talk ng is NMEA 2000 with a smaller connector. You can get an NG to 2000 cable. You need the T122. That gets you NMEA 183. If you need NMEA 2000 input than you need the Actisense converter. another $200. Airmar makes all the transducers. You can get a NMEA 2000 compatible with your plotter. You can also connect the autopilot with an NG to 2000 cable. I recommend you do it so you can steer to a waypoint.
