1. Plug it into the car cigarette lighter socket, and it will turn on automatically.
2. Connect your mobile devices with this car Bluetooth transmitter or insert a USB flash drive into the transmitter.
3. Tune your car stereo to a blank, unused FM frequency. The standard is a slight rustling sound.
4. Adjust the FM transmitter to the same frequency. At this time, the car radio will be very quiet, with no static interference. (If it’s still not quiet, try to find a new blank channel again)
5. Then you can listen to songs from your phone and make hands-free calls on your phone.

1. Try a few more clean empty channels to match, only rustling sound, no human voice and radio interference are clean empty channels.
2. Adjust the transmitter FM channel to be exactly the same as the car FM channel.
3. Turn down the volume of the car speaker, and increase the volume of the mobile phone and car Bluetooth to reduce noise appropriately.
