Jansicotek BC71 Car HD Radio

The Jansicotek BC71 is a Bluetooth FM transmitter that adds wireless audio streaming and hands-free calling to a factory stereo. It plugs into a vehicle accessory socket and draws power while broadcasting music or calls on an unused FM frequency between 87.5 MHz and 108.0 MHz. A digital display shows real-time battery voltage and current volume level. Colorful LED backlighting can be switched off when only charging is needed.

Drivers who want Bluetooth 5.0 streaming

This adapter suits drivers who want Bluetooth 5.0 streaming, dual USB fast charging up to 36W total, and a voltage readout without replacing the head unit. It also supports TF cards up to 64G for offline playback. Buyers who need an auxiliary input, a DAB+ tuner, or a dedicated installation kit should look at other solutions.

FM frequency range 87.5 MHz to 108.0 MHz

The transmitter operates across the full 87.5 MHz to 108.0 MHz band, so you can select any clear channel for audio relay. If local spectrum congestion makes it difficult to find a clean frequency, the device cannot guarantee interference-free playback.
