Glad I found this. I found a discussion about all the problems encountered when downloading music onto a USB stick and using it with the Mazda Connect system. I have a Mazda 2021. Secret? The flash drive cannot be larger than 8 GB. I have tried many large sizes and all have failed. Just format it to FAT 32 and put your mp3s in and you're good to go. I'm a Mac guy, so I didn't need some programs that Windows users need. Easily convert songs to MP3 in iTunes. This resulted in correct file names and graphics. Sweet. I don't like pairing phones with built in audio systems.
