What USB format to play mp3 on my car Pioneer stereo player?

What USB format to play mp3 on my car Pioneer stereo player?

FAT32 works on my Pioneer---you will likely get an error message otherwise. As I recall it might be "error 24".

I've been told that some quite recent car players will work with NTFS---mine is 4 years old and requires FAT32.

Give some thought to how you want to play back.

Totally random play from a pile of individual mp3s?

Random play from within a bunch of different folders?

Alphabetical order by artist name from within a bunch of folders?

Numerical order based on tags of some type?

Etc.

The controls on car players are difficult to access while driving due to daytime glare and reflection and because the buttons are so small and fussy. You've got a decent chance of killing yourself or someone else if you try to use the controls while driving.

Some brands have a fairly low restriction on the total number of different folders allowed.

The restriction on the total number of songs allowed can also vary by brand.

I've settled on this:

I don't use a folder structure at all. All of my mp3s are just laying there in the root of the USB stick.

All mp3s are just individual songs. No "albums", no "CDs", no "playlists".

All playback is purely random. I never know what is going to come up next and I like it that way.

I don't have to use any control other than the standard volume knob.

My particular Pioneer model has a 14,999 total songs allowed limit. Yours may differ.

Thanks everyone for the responds. I tried all formats but still get ERROR 23. I did a search and it turns out.

SOLUTION: the USB needs to be convert to MBR and FAT32.
