Welcome to our store! High fidelity. Anti-interference. Great signal. Stereo extended. Pure and clear music quality. The 3.5mm plug on the cable connects to the car's AUX interface, and the USB interface connects to the U-disk. Enables automatic playback of songs from the USB drive. Not all cars with this interface can use this type of cable. Some cars have AUX without decoding function, so can only use MP3 device, (only the car's AUX interface that has the function of reading U-disk can use this type of cable) When using, it is best that the U-disk does not store too much, specifically for how much capacity the car's AUX can support. The U-disk must not have other documents inside and must not create any folder. Songs in MP3 format are used. 100% New & High quality Category: D3.5 Audio Cable Connection: D3.5mm-USB Length: 21cm Color: Black Material: plastic + metal Package includes: 1 x 3.5mm AUX Audio Plug Jack to USB 2.0 Male Conversion Cable Cord Note: Light and different displays may cause the color of the item in the picture to be a little different from the real thing.
