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.
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:
