Frequently Asked Questions

Q: Will this USB to AUX adapter cable work with any car stereo?

A: This cable works specifically with car stereos that have a 3.5mm AUX port capable of reading USB flash drives. Standard AUX-only ports that only accept analog audio signals will not support USB flash drive playback. Check your car stereo's manual to confirm USB-over-AUX compatibility before use.

Q: What audio formats does this cable support?

A: This adapter supports MP3 format audio files. For the best experience, store only MP3 music files directly in the root directory of your USB drive without creating folders or storing unrelated file types.

Q: Can I use this cable to charge my phone or other devices?

A: No — this is a data/audio adapter cable only, not a charging cable. It is designed solely to allow your car's AUX port to read and play MP3 files from a USB flash drive.

Q: How many cables do I get in a pack?

A: This listing is available in 1, 2, 4, or 6 packs, so you can choose the quantity that suits your needs — great for keeping extras in multiple vehicles or as backups.
