Having troubles getting my two Helixs networked together. I have all the correct ethernet cables connected to both graphs but my 10 si g3n will not show the Helix 7 g2n anywhere. I have a ycable with a the chirp sonar from the all season pack connected to the 10 si g3n. I do not have a transducer hooked up to the Helix 7, only the networking and power. If anyone has a fix for getting them to speak please feel free to let me know. I am stumped and my dealership was as well. Thanks.
