Questions about this item
What USB storage device do I need to play music with this adapter?
You need a USB flash drive under 8 GB formatted with only MP3 files; larger drives or other file types will not work.
Will this adapter work if my car's AUX port lacks built-in MP3 decoding?
No — the cable only functions when the car's AUX input includes an MP3 audio decode function; without it the adapter cannot play audio.
How can I confirm the adapter is working after I plug it in?
Insert the 3.5 mm plug into the car's AUX IN jack, connect a compatible USB flash drive, and music should begin playing through the car speakers.
