I wanted to update with boot up picture and wallpaper. It took me eight USBs and I had a consult the Internet. I thought All of the USB drives that I was using were FAT32 but they were all bigger than 32 GB. My Computer would not even let me format them to FAT32 unless they’re smaller 32 GB or smaller. So the USB drive needs to be smaller than 32 GB and needs to be reformatted to FAT32 if you want to update the radio from SJoyBring. I thought all brand new drives would work but needed to be a new drive smaller than 32 GB and formatted it to FAT32. Anyway they didn’t explain it in their instructions I just didn’t think it was important so it took me longer to do the update the necessary. Just follow their instructions they are very helpful and it looks so cool with my new pictures. Thank you😊👍
