The file manager isn't very intuitive, you need to navigate to the source file, highlight select and press menu so the file has a + beside it, then highlight copy and then press menu again, now navigate to the destination directory and move to any entry and then paste should be selectable. After you have pasted, be very careful because it highlights the next available operation which just happens to be "delete"!!
There's a youtube video showing how to use the file manager somewhere.
If you are still having problems, I can make a testmode script to do the copying.
For AVIC MRZ99 I could copy from SD but unable to paste into directory so I downloaded and tried using the installer changing paths to SD. Installer only changed image file but not language files, it gets stuck in a loop on image file. Is there an updated installer for SD so I can get the language files into both user directories?
