How many files can be stored in a USB storage device to play back music from it on the audio system?
Up to 30,000 tracks can be stored on a USB device for it to work with the audio system for music playback.
NOTE: For the CMT-SBT20 and CMT-SBT20B units, up to 999 tracks can be stored.
However, when an excessive number of files other than music tracks are stored, or when the folder structure is complicated, it may take a long time to read files causing the playback to be unable to start.
