At last my ultrafit 32gig is working with my car audio, pioneer.
I initialized the USB and create a new primary partition
And then format it for FAT32
What I did was,
- using diskpart (be CAREFUL when you do something with diskpark not to erase the other disks)
-
list disk
-
sele disk (### of your usb disk)
-
clean
-
create part primary
- Format USB as FAT32 with Windows Explore
I am not sure it will also work for others.
