The medium formats supported by the radio are ISO 9660 Level 1 and Level 2 and includes the Joliet extension.

When reading discs recorded using formats other than ISO 9660 Level 1 and Level 2, the radio may fail to read files properly and may be unable to play the file normally.

UDF and Apple HFS formats are not supported.

The radio uses the following limits for file systems:
• Maximum number of directory levels: 8
• Maximum number of files: 255
• Maximum number of folders: 100
• Maximum number of characters in file/folder names:
• Level 1: 12 (including a separator . and a threecharacter extension)
