I was asked if I could send a guy my C_Map FP card reader and the associated PCPlanner software. I have one, but will not loan it out as I need it to help my customers read or write their old Furuno Proprietary cards. If anyone has one of these and can spare it, let me know at [email protected]. I have contacted Furuno and C_Map and they couldn't help. Searching the internet was fruitless. This caller was so desperate, he wanted to borrow my reader, send it to a company in China to disassemble it and make a copy. I got mine from a customer that no longer needed it some years ago. I know that the Furuno RDP 139 uses the FP card.
