Car HD Radio with Bluetooth 5.0

The ESTONE BC71 is a car HD radio kit that adds wireless audio streaming and hands-free calling to a factory stereo. It combines an FM transmitter with a TF card player that supports WAV and FLAC lossless files. A dual digital tube shows the FM frequency and the vehicle battery voltage in real time. Colorful LED backlights provide visible controls in low light.

Suited for drivers who want lossless playback

Commuters who rely on streaming services can pair a phone over Bluetooth 5.0 and use the voice-assistant button for hands-free control. The dual USB ports deliver QC 18W and PD 18W outputs for rapid device charging. Buyers who need an integrated navigation display or a dedicated DAB+ tuner should look at a different product class.

FM usable sensitivity 11.2 dBf

This sensitivity figure determines how cleanly the unit receives weak FM stations in fringe areas. The tuner covers the full 87.5 MHz to 108.0 MHz band with stereo FM transmission technology. AM sensitivity is rated at 21 uV for talk and sports reception. Matching this spec to local signal conditions decides whether the BC71 is the right adapter.
