FM car transmitter ART FM-84B with Bluetooth, USB and MP3 playback

ART FM-84B is an in-car FM transmitter designed to add Bluetooth audio streaming and USB MP3 playback to vehicles without modern media inputs. The device pairs with a smartphone over Bluetooth to enable hands-free calling and wireless music playback, while also reading MP3 files directly from a connected USB flash drive. Audio is transmitted to the car stereo via a selectable FM frequency, providing a simple retrofit solution for older car radios.

Advantages

The transmitter combines Bluetooth wireless connectivity and a USB MP3 player in a compact unit that plugs into the vehicle power socket. It supports stable Bluetooth audio streaming and hands-free calling, as well as playback control for MP3 files stored on a USB drive. Frequency selection allows you to choose the clearest FM channel for minimal interference, and the device’s straightforward interface makes operation simple while driving.

Suitable for

• Vehicles without auxiliary (AUX) or USB audio inputs
• Users who want wireless audio streaming from smartphones
• Drivers who need hands-free calling during travel
• Playing stored MP3 music from a USB flash drive

Key specifications

• Bluetooth wireless audio streaming (A2DP compatible)
• Hands-free calling support (built-in microphone)
• USB port for MP3 file playback from flash drives
• FM transmission to car radio via selectable frequency

How to use

Plug the ART FM-84B into the vehicle’s 12V power socket. Select an unused FM frequency on your car radio and set the transmitter to the same frequency. Pair your smartphone with the transmitter via Bluetooth following the phone’s pairing procedure; once connected, use the phone or the transmitter controls to play audio. To play MP3 files from a USB drive, insert a compatible FAT32-formatted flash drive containing MP3 files into the transmitter’s USB port and use the transmitter controls to navigate playback. For hands-free calls, accept incoming calls using the transmitter controls or your phone; the built-in microphone will handle voice pickup.

Usage recommendations

For best audio quality, scan for the clearest FM frequency before each drive and position the transmitter for unobstructed Bluetooth signal to the paired device. Use a USB flash drive formatted to FAT32 and keep MP3 files organized for faster navigation. Avoid using congested FM channels to reduce static and interference.
