Gemini CDM-4000BT – MP3 Playback Order Not Matching File Names

Problem:

My MP3 files are named in a numbered sequence (e.g., 01_song.mp3, 02_song.mp3, etc.), but the CDM-4000BT does not play them in that order. How can I control the playback sequence?

Quick Explanation:

The CDM-4000BT does not sort MP3 files by filename or ID3 tags. Instead, it plays files in the chronological order they were copied to the USB flash drive. This behavior is determined by how the file system stores data, not by how files are named.

Quick Solutions:

Copy Files One-by-One in Desired Order

To ensure playback follows your intended sequence, copy each file individually to the USB drive in the order you want them played.

Use a File Sorting Tool

If you've already copied files or want to automate the process, you can try using a utility such as:

• DriveSort
• mp3DirSorter

Note: These are third-party tools not affiliated with Gemini. Use at your own discretion and risk.

Avoid Relying on File Names Alone

Even if files are named sequentially, the CDM-4000BT will ignore this unless the copy order matches. Renaming alone won’t affect playback order.
