Hello.
I have notice that audio files are not listed and displayed in the correct order into the CQ12T player.
I have order my set list of song with file named from 001 to 023 into the USB stick and the first file into the player is 023 (second 016, third 002 etc…).
The audio files are picked up in their order on the drive, which generally speaking is in the order of copying them over.
If you copied multiple files to the drive at the same time, it sounds like the computer first copied 023, then 016, then 002 etc…
My car audio player used to have that “feature”, it seems like a basic bug in the software development that a developer should fix before release. Anyway I found a program that will re-write the files onto the USB stick in order to get round the issues.
