I believe you mean 03P9271 (008-565-390)
It is available from any authorized Furuno dealer, but I am guessing you are looking for a used one?
Yes. The PC Board I am looking for is 03P9271 (008-565-390) Thanks for clearing that up
No wonder I couldn't find it! Just checked the price, but at $365:- they don't come cheap.
