MP3/FM Modulator and Car Charger M42

The MP3/FM Modulator and Car Charger M42 is a practical device that enables older vehicles without factory Bluetooth to enjoy wireless music streaming and handsfree calls. It plugs directly into the car lighter socket, connects to your phone via Bluetooth 5.0, and then transmits the audio to an empty FM frequency set on your car radio. The blue four-digit LED display constantly shows the active frequency, making tuning quick and highly visible.

A key feature of this modulator is the handsfree calling function using the built-in microphone and car speakers. A dedicated button with a green call icon is used to answer and end calls, while the central rotary knob and arrow buttons allow you to control your music without touching your phone. In addition to streaming from your phone, you can also play music directly from a memory card via the narrow slot on the housing.

The device is equipped with three charging ports — two USB-A and one USB-C, allowing the driver, passenger, and an additional device to charge simultaneously. The RGB light strip along the edge of the black plastic casing provides discrete ambient lighting during night drives. Its compact shape with a tilted front panel ensures it won't obstruct the gear shifter, making it an ideal solution for daily commutes and longer trips.
