How to attach Navnet 3D to GP330B antenna?

Was told this is the correct antenna, but I do not see a port in the back of the display that fits the male cable end on the antenna. Not sure what am missing. I also have a Hub 101.

Thanks

Two types of GP330B are made. One (GP330B) is NMEA 2000 and must connect to a properly established bus. The other (GPS330B/0183) is NMEA 0183 with 7 pin connector that could connect directly to most Furuno 7 pin NMEA input ports like data one of the NN3D. Which did you purchase?

This is what the cable looks like.

That is a NMEA 2000 device connection at one end and the GP300B connection at the other. you have a GP330B (NMEA 2000) unit. It would need to go into a TEE connection on your NMEA 2000 bus. If you don't have an open tee on your 2000 bus, then you would need to add one. If you don't have a 2000 bus then you would establish one with a NMEA 2000 starter kit like p/n AIR-033-745. The only other option would to be buy the 0183 cable (AIR-339-103) and replace the 2000 cable for 0183 type then go directly to data port one of the NN3D unit. I assume that someone wanted 2000 version or it would have been ordered with the 0183 type to begin with. NMEA 2000 is nice because other items on the bus can see the GPS even if the NN3D is turned off.
