I have a opportunity to pick up a Onix 10ci si Cross Touch. What extras do I need to connect it to my Ultrex with I-pilot link and Us2 and the HB TM 360? Does the cables have to run thru an Ethernet box or will they connect directly? Was looking for 2D sonar, HB 360 and I-pilot link functions from the Onix. Tks guys!
