I am going to network helix units on the bow and console. Helix 9 si mega on console and helix 10 sonar gps with 360 image linked to Ultrex trolling motor. I know I need the Ethernet hub to link everything together. Has anybody done this and where did you place the hub at? Also has anybody put Icommand gauge in and does this just link thru the hub as well. Or can you just use the NMEA 2000 link to the motor thru the Helix unit. Which one is better?
