Recently I had an unpleasant experience with my Pioneer DEH-159OUB car stereo when I inserted my SanDisk Ultra Dual USB Drive 3.0 16 GB to play some music.

Each time when switched the mode to USB, it was displaying ERROR 23, again and again, no matter what I did. It was a long drive that I was up to and unfortunately drove without playing a single song because of that error.

Quick Tutorial:

 

 

 

What is USB Error 23?

The following error shows up when the stereo doesn’t detect the USB device which we insert or in other words the Files system of the USB is not recognized by it.

Soon after when the error was encountered, I recalled back and spent hours thinking what else I did with my USB flash drive which was causing the error and finally got the answer.

I had made my flash drive bootable using RUFUS which changed the format of the thumb drive to NTFS, and when my job was finished I simply copied my songs folder in it and started packing up for the journey.

How to fix USB Error 23?

So here are the simplest steps to bypass the USB ERROR 23,

1.  First thing first, connect your USB flash drive to the PC & backup what’s inside!!

2  After that, Right-click on the drive and click Properties. Where you can see that it is not the same format that the stereo supports (which is FAT 32).

3 Now close the properties window and right-click on the drive again and hit the format option. (As shown in the figure)

4 Change the File system to FAT 32 (Default) and hit the Start option.

Note: the above step will delete all the files in it (that’s why we did the backup of the content before).

5. Done!!! Just copy your music files back to your flash drive and connect it to the stereo again, there will be no sign of ERROR 23 from now. Down below is a quick tutorial for fixing the following error.

Note: Even after following the steps still the error is showing up, then probably the problem is with your USB thumb drive.

You can simply run a check using free tools like windows Check Disk (CHKDSK) to see what’s wrong with the device.

Sometimes lots of bad sectors present in drives causes performance degradation.

Change your partition

If the above methods fail you need to check your partition system of the thumb drive. If your thumb drive has GPT partition then your pioneer system won’t be able to recognize it. You need to convert into MBR for the same, check out this detailed tutorial down below for changing your partition:

  1. My USB stick doesn’t have FAT32 (default), it only has NTFS and exfat (default). Should I pick the exfalt?

      • Larger USB sticks don’t offer that option by default but you can use a third-party program to do FAT32 formatting. I downloaded a program that’s literally called “FAT32 Format” and it works nicely.

    fix error 23:
    1-file system:fat32
    2-partition scheme: MBR (Important.Important.Important…)

    • My USB drive was formatted in FAT32 but I was getting that error 23 .. Until you pointed to the partition scheme and I remembered I’ve made it GPT in RUFUS.. Converting it to MBR fixed that error. Thanks a lot..

  4. Tried all mentioned steps and solutions above to no avail. Still does not work for me.

  5. forget an important detail if you use your USB Pen to listen music, then if you format it with windows 10 professional … you have to change MBR to GPT partion… that happen to me :), when i formated back to music … i have that error 23 .

  6. Didn’t work for me. I was getting Error 23 so I took the usb and plugged into my pc and tried to reformat it, but the pc was saying it was unable to reformat the usb.
    So i got a completely different empty usb (fat 32) put some songs on it and tried it. Got the same message ‘error 23’.

  7. What if I don´t have a computer or USB drive to fix the error? I have no music downloaded on the stereo, it just says error 23 MTP Connection. How can i fix this?

  8. I had same problem tried everything you said didn’t work so i downloaded the EaseUs partition manager and worked absolutely fine thanks. Andy

      Thanks for your response, it will be of huge help for others!!!

  9. I tried this but y problem is a little different and it didn’t fix it. When playing the USB it cuts the songs short. It is so frustrating! The usb plays fine on other devices. Any suggestions please? I have formatted to fat32 and put the songs back and it still does it.

    My USB disk does not have the option to format to FAT32, only NSFT or Exfat.

    • It’s a trick of Windows that prevent people to format in Fat32 for high capacity storage (apparently more than 32Go).
      You have to use a tool like Easus Partition Master or equivalent.
      The theorical limit of Fat32 is 16Tio so it should be ok !

  12. thax its error 23 created by pendrive formet.make it fat32 (default) in formet option

  13. Tried both solution but still i get error-23…. Something else?

  14. Does this work with CDs too? Because I tried burning a CD and when I put it in my truck to play it, it says Error 23 and my format was already the way it should be at the FAT 32 ( Default )

  15. Thanks a lot, my friend. You’re the best. God bless you for helping others.

  16. I am not even able to do the backup in the PC. Is asking to format it. I would love to retrieve the music that I have there. WHat else I can do?
