I would like to install a stand alone class B AIS unit with display on my boat. Since I do not have room at the binnacle for the display I need my MFD12 to display the main information. I was thinking of getting a unit that had N2K output as I thought it would be easier to get the information to the MFD over the network but I have been told that the NN3D displays may not interpret AIS data sent over N2K. Is that the case? Do I need to provide AIS data to the MFD12 via NMEA 0183. Need to know before I make the purchase.
