if your 17x antenna is already run from a 3xxx unit, you can wire it into the wiring harness, you do not need to use the nmea 2000 antenna - all the other boxes still use the garmin marine network and are not nmea 2000 devices, The weather and sounder will hook up fine.

Download the garmin install manual from garmin.com - support to see all this....
