I hope it's okay that I'm posting in this "Troubleshooting" forum rather than the Audio and Electronics forum, but this has nothing to do with an upgrade. I loaded some audio files onto a USB stick so that I could listen to them in my car, but when I insert the USB stick, the radio doesn't see it. I know the port itself works, because when I charge my iPhone in it, it also starts playing any music files on the phone until I disable it. At first I thought it might be the formatting of the stick, so I erased and re-formatted it to FAT32, then loaded the files onto it again. No dice. Could it be that I'm loading .wav files rather than .mp3? It's a 16GB stick. Is there a size limit? Any other thoughts?
I believe that it will support 16GB FAT32. I would suspect that you need .mp3 rather than .wav format. I also understand that it can't handle folders than contain more than 255 files.
What worked for me was to copy the software from one of my mp3 players to the USB drive. Then load music.
Thanks for the replies. I did notice in the Prius radio manual that it said it will play .mp3 or .wma (no mention of .wav), so I converted them all to .mp3 and it's happily playing everything fine now. On a side note, I'm still amazed that even after I remove the flash drive from the car and reload more files onto it, it still will pick up exactly where I left off in the middle of one of the previous files when I put the drive back in.
I just took possession of my new 2019 Prius Prime Advanced. I have a 16GB usb thumb drive formatted Fat32 with about 4 GB of mp3 files stored in folders by artist. When I select USB as the source in Entune and select Browse it never gets past the "cataloging" stage. If it does play one song, it never plays another. I'm going to try formatting exFat and see if it fares any better. By the way the usb stick performed flawlessly in the Alpine after market unit in my old Subaru.
You appear to have posted this in the wrong forum. Prius c and Prime are very different cars. The audio systems are similar but not identical. You can ask a moderator to move it, or just re-post in one of the Prime forums. Catalog errors are usually metadata related- invalid character set or corrupt album art. Maybe make up some test files with no art etc.
