What about the place you purchased your electronics from?
That'd be a negative. I had a guy who did some other work for me tell me he could do it. Then of course after I buy the set, he says he can't do it. I talked to Octopus at the boat show and they said they no longer handle customer supplied installations and the other I've been seeing more negative reviews than anything. I am talking now to another outfit that can do everything I need done. Just waiting to hear back from them
