i got my Clarion installed this past weekend, but something seems to be wrong with the order it handles MP3's in. for example, i download a 4 hour talk show each day and break it up into 10 minute chunks...my other head units (offbrands SoundStorm and Boss Audio) could handle the files in order with no problems, but the Clarion will play the following:

20090408-01.mp3
20090408-02.mp3
20090408-03.mp3
20090408-04.mp3
20090408-08.mp3
20090408-05.mp3
20090408-09.mp3
20090408-06.mp3
20090408-07.mp3
20090408-30.mp3
etc.

any ideas why this would be happening? i DO NOT have random (aka "RDM") turned on at al...btw, even if random was turned on, according to the CSR (and i confirmed this), it only randomly moves to a different track if you let the tracks play all the way through...if you manually hit next, it will simply go to the next track. all the ID3v1/ID3v2 tags are correct and it seems like tracks 1 - 4 play fine, but after track 4 (ie, 20090408-04.mp3), it will jump all around...it does this for EACH day...i separated the days into their own folders and have ~30 tracks or so per folder for each day.

i even grabbed a different USB stick and copied over the files using Total Commander (which i watched put the files on in order, whereas Windows Explorer doesn't always write files in order of filename) and the same thing happened.

the CSR i talked to at Clarion has never seen anything like this...anyone else have any ideas? i download a lot of talk radio and can't live with the Clarion bouncing around tracks after track 4 is done.

thanks for the help...sturmie

in case anyone is interested, here was the problem and resolution to my issue:

CAUSE: on some portable MP3 players and stereos, the lack of resources (CPU, memory) can lead the developer to make it display or play the files in the order in which they are on the disk...especially if the system reads filenames only instead of ID3 tags. since my LFN (long filename) was over 8 characters for my files, the file table seemed to have converted the SFN (short filename) into some sort of hash code (?) where 20090408-01.mp3 became something like 2DA4F6T1.mp3, 20090408-02.mp3 became 2EA4Q6X7.mp3, etc. and after 20090408-04.mp3, the SFN was out of order.

RESOLUTION: someone wrote an application, called DriveSort (http://www.anerty.net/software/file/DriveSort.php), that specifically addresses this issue and allows you to edit the SFN in the file table of your flash drive. using the app, i was able to change the SFN to 00000001.mp3 and have it rename sequentially in correspondence with the LFN using the "PlayList Mode" in DriveSort.

just thought i'd post this since there may be a few others in the same boat.
