My question for those that have installed a Hummingbird 360, what did you use for the power source? Did you run a direct wire from the battery or splice in to another power source? I powered my Hydrowave from the Helix unit but was told to put an on/off switch and fuse in for the 360. I haven't bought one yet but considering it, just want to get my plan together in case I do buy one. I have delayed buying one thinking they'll come out with newer version and I'm sure as soon as I do buy one they'll update it.
