I'm Upgrading all of my electronics, and still have the working radar system.
Its a Simrad RA 41C with large Color LCD Monitor
Its listed on eBay for $450.00, but I would end the auction early and sell it to a GB Forum member for $350.00.

My electronics tech said that any knowledgable electronics tech can get the correct cables and ends and cut them to the length that you need and terminate them properly.
