Upgrading GP320B to GP330B, NN3D

[erikj725]

Hi, I'm contemplating replacing the GP320B with the GP330B due to the time/date problem and maybe a problem with the Mag Var that is preventing my SimRad autopilot from steering to a waypoint.

It looks like there are two GP330B to pick from. The "standard" which is for NMEA2000 and the "0183" which seems to come with a cable. Since my older GP320B is already wired directly to the MFD12, which GP330B should I purchase? I'm guessing I can re-use the existing cable and just plug it into the standard GP330B? I.e., no need to buy the "0183" version?

Thanks!

The GP320B was a NMEA0183 antenna. The GP330B is NMEA2000 and would require a NMEA2000 network. The GP330B/0183 is NMEA0183 and would connect the same as your current antenna.
