WTV020 MP3 player

One important note!  These units only work with SanDisk SD cards, 2 gig or less, which are not easy to find. Micro SD also!

If this saves you trouble thank one of our customers.

We do have a 32 gig version, check out related products below.

Here is a version that actually works with common media, and we have another with an SD card slot, full size SD.

Or create a folder on PC and copy all music files to the folder. Add prefix 0000~9999 to the file names like 0000-my-song.mp3, 0001your-song.mp3, 0002thier-song.mp3 and so on. Then reorder the music by name. Select all files (CTRL+A), then copy (CTRL+C ), and paste these files onto the SD card/U-disk. Using this method, the music files should be stored in the desired order.
