Play Order in in-dash CD-MP3 player

I've been digging around everywhere trying to find a forum that deals with in-dash CD-MP3 players, and couldn't find much. I didn't know if you guys could help me with this question though...

I've got an in-dash CD player with MP3 capability, and I've burned a CD with multiple tracks on them, arranged in directories, similar to below:

DIR1\TEST1\Track A 01.mp3
DIR1\TEST1\Track A 02.mp3
DIR1\TEST1\Track A 03.mp3
DIR1\TEST2\Track B 01.mp3
DIR1\TEST2\Track B 02.mp3
DIR2\........

And so on... you get the point.

And so I pop it in my CD player, it reads them all, (in each individual subfolder too), and I can skip between folders (like I can select TEST1 folder, then Track A 01.mp3, or skip to Track A 02.mp3).

But the problem comes when I go through the files, it's SUPPOSED to read the files like "Track A 01.mp3, Track A 02.mp3, Track A 03.mp3"... but sometimes it gets them out of order, for no particular reason, like "Track A 02.mp3, Track A 03.mp3, Track A 01.mp3".

I've checked the filenames and they're all proper, I checked the dates, etc, etc... but for whatever reason, some folders will get mixed up and out of order, and I've no idea why.

I've already :rtfm: through completely, searched all over the internet (maybe I'm not searching for the right thing though, I dunno), but can't find a single thing on how to tell either the CD to put them in a certain order, or how to tell the CD Player to read them in a certain order.

Thats a question to ask customer support of who ever built your head unit. Unless its Frodo Player or Winamp I dont think we can be of much help.

I think I'm just going to combine each original disk into one MP3
