[CA] [CA11] C80 import problems

[Polymela]

I have a 'new to me' boat with a C80 Display. I am trying to import waypoints and routes from RayTech Planner version 6.2, build 6355 to a Raymarine C80 MFD (app version 3.18). I am using a SanDisk 128 MB Compact Flash disk which has been formatted with FAT. The Archive.fsh file is 1,025KB in size. I can export from RayTech but when I try to import to the C80 I receive the error message ‘Retrieve Failed’. The archive file does not display on the C80, it appears the MFD does not recognize the compact disk. I have also tried to export from the C80 onto the Compact Flash card and received the same error message. I have searched the FAQ and see a reference to a format utility, but cannot find the utility. Any ideas why the export/import will not work?
