HD Radio Kit for Factory Stereo

The ESTONE BC71 is a car HD radio kit designed to integrate with a factory stereo system. It adds Bluetooth 5.0 connectivity for hands-free calls and audio streaming. The unit supports TF card playback of WAV and FLAC lossless files. A voice-assistant button wakes Siri or Google Assistant on a paired phone.

Thermals Noise and Power Draw

The adapter delivers up to 36 W total through two fast-charge ports. A USB-A port provides QC3.0 output at 18 W, while a USB Type-C port supplies PD 18 W. A dual digital-tube display shows real-time battery voltage so the driver can monitor the vehicle electrical system. Colorful LED backlights illuminate the controls.

Build Fit and Freedoms

The transmitter operates across the 87.5 MHz to 108.0 MHz FM band with 11.2 dBf usable sensitivity. AM reception offers 21 uV sensitivity. Stereo FM transmission technology sends audio to the car radio without auxiliary cables.

Questions about this item

How do I install the ESTONE BC71 and which step do people often miss?

Insert the unit into the vehicle's power socket, then press the multifunction button to pair the phone via Bluetooth 5.0 before selecting an FM frequency.

What maintenance or replacement will the ESTONE BC71 need over time?

The TF card slot and USB ports may collect dust; clean them occasionally with compressed air to maintain reliable playback and charging.

Which limit appears first during sustained use of the ESTONE BC71?

The combined 36 W output across the QC 3.0 and PD 18 W ports is the ceiling; drawing more will trigger protection and reduce charging speed.
