Car HD Radio with Bluetooth 5.0

This ESTONE BC71 car HD radio adds wireless audio streaming and hands-free calling to a factory stereo. It receives FM signals from 87.5 MHz to 108.0 MHz with 11.2 dBf usable sensitivity and AM signals at 21 uV sensitivity. Bluetooth 5.0 connects phones within 10 m for music and calls.

Drivers needing fast charging and voltage monitoring

The dual USB ports deliver 18 W via QC3.0 and 18 W via USB-C PD for simultaneous device charging. A digital display shows real-time battery voltage and FM status at a glance. Buyers who want built-in navigation or a multi-speaker amplifier should look at other solutions.

FM usable sensitivity 11.2 dBf

This figure determines how cleanly the unit picks up weak stations in fringe reception areas. The tuner covers 87.5 MHz to 108.0 MHz with AM stereo separation supported over Bluetooth 5.0. If local signal strength is marginal, this sensitivity level is the key spec to evaluate.

Questions about this item

What comes in the box and what do I need to buy separately for audio input?

The package includes the BC71 transmitter with dual USB ports and dual LED displays. For wired audio you must supply your own TF card or AUX cable.

Which charging version should I choose between the USB-A and USB-C ports?

Both ports deliver up to 18 W; the USB-A port uses QC 3.0 and the USB-C port uses PD, so pick the one that matches your device's fast-charge standard.

What does the 36 W maximum power figure mean when the unit is running in my car?

It is the combined peak output of both ports — 18 W from the QC port plus 18 W from the PD port — allowing two devices to fast-charge at the same time.
