The BF805 Bluetooth FM Modulator is a device that allows you to wirelessly connect your phone or other Bluetooth-enabled device to your car's audio system. It works by transmitting the audio signal from your device to an open FM frequency on your car's radio.
To use the BF805 Bluetooth FM Modulator, you simply plug it into your car's cigarette lighter socket and tune your car radio to an unused FM frequency. You then connect your phone or other device to the modulator using Bluetooth. Once connected, you can play music, make hands-free phone calls, and use other audio apps through your car's speakers.
