Currently I have a Gen1 HDS7 w/ LSS-1, LGC4000, NMEA 2000. I'm adding a HDS5X to the bow to utilize my Ultrex US2 xducer. My question is: should I leave the HDS5X out of the NMEA network? I really only use the LSS-1 while idling from the console and will probably just use the HDS5X as a front graph while fishing. (Or am I missing an advantage of including it in the network.) I've read the X models don't have the chart plotter ability. Thanks for any advice! Scott
