Product description






Easy Frequency Tuning: Simply plug the FM transmitter into your car’s cigarette lighter port to display voltage and frequency. Press the CH button for frequency adjustment, and use the phone buttons to select your desired channel.
Effortless Bluetooth-Compatible Pairing: To connect this MP3 player for the first time, enable Bluetooth-Compatible on your phone and search for “BT23.” Click to establish a connection, and if needed, input “0000” as the password.
Multiple Playback Methods: After successful pairing, enjoy music from your MP3 player or a USB drive (supports MP3/WMA/WAV/FLAC formats). The USB must be in FAT32 format and should not contain folders.
Seamless Source Transition: To change from Bluetooth-Compatible to USB audio, insert the USB and allow 3 seconds for automatic playback. To revert to Bluetooth-Compatible, press the MP3 player’s power button and wait 3 seconds. Repeat to switch back to USB.
Car Battery Protection: While this FM transmitter is designed to conserve your vehicle’s battery, it is recommended to switch it off or disconnect it when not in use. Ensure other electrical devices, such as headlights, are turned off.
