I have a Lowrance LCX 111c chart plotter. Bought it from a marina. It came with the GPS puck LGC-2000. Can anyone tell me what cable I need to connect the two? I called a Lowrance tech support person, who barely spoke english, and he said it was not made anymore. The part # he gave me was for a network block. Not a cable at all. The cable will have double males with 5 pin connectors..Thanks for the help!
