To use the PWRSync 3.5mm AUX Cable in your car, as well as most other AUX cables, you only need to follow a few quick and easy steps. Check that your car has an AUX port or other means of connection for AUX cables – most cars are equipped with an AUX port for playing your favorite songs. Gently wipe the AUX port, the cable, and your device with a soft, dry cloth. Firmly insert one end of the cable into your device, then insert the other end into your car’s AUX port. Make sure the cable is securely and properly connected, and you should now be able to play all your favorite tunes while you’re on the road through your device!
