Will a XTM 9 SI 180T work on a 859 ci HD DI ? This is a question I can not get anyone to answer.... Google don't know and humminbird support must be REALLY backed up.

And one more. I'm trying to network an 1198 and this 859. Will the adaptor cable used to link 798 and 1198 work to link the 859 with the 1198 or will I need a different cable???

Why can't everything have standard hook ups????
