When BMW NBT plays songs on a USB flash drive (or solid state drive), it will find that some tracks are repeated, and even two or three songs will be displayed. ...
Reason: Repeatedly plugging and unplugging the USB flash drive or solid-state hard disk to copy songs to the computer. This can't be blamed on NBT, because some content is cached to speed up playing and reading!
Solution:
When copying songs from a USB flash drive or a solid state drive to a computer, the name of the SD card was changed by the way after the songs were copied.
For example, if the default has never changed, the name of the U disk should be "USB". After the song is copied, you can change it to "BMW" or any name you like. Anyway, it's different from before copying. When the u disk is reconnected with the USB interface of the hand-held box in the car. You will find that NBT will reread the contents of the USB flash drive. At this time, the track will not be played repeatedly.
If there are many tracks, for example, I use a solid state drive, the tracks are about 18000 FLAC songs, and it takes about 1 minute to read. If it is an ordinary tens of GB USB flash drive, the reading may be slower. Please be patient. ....
Above, I hope to solve your problem!
