Used Autohelm 6000 course computer. I don't have the provisions to system-test anything pre-SeaTalk, so I'm selling this for parts. I have no history on the unit and do not know what, if anything, is wrong with it. Came in a big shipment from a former Raytheon dealer. Good spare parts or repair project.
