Replacing a Raymarine C80
I have a 2008 Rinker 330 EC with a Raymarine C80 chart plotter that is no longer working. I am looking to replace. I spoke to chart plotter supplier and he is asking me what model of DSM (Digital Sounder Module) I have feeding the C80. I followed the wire where I could but couldn't find one. Does anyone know to narrow the search? Or even if Rinker used one?
