Product Purpose

The LUOM BC71 is a car HD radio kit that adds Bluetooth 5.0 audio streaming and hands-free calling to a factory stereo. It targets drivers who want wireless music playback and safer phone use without replacing the original head unit.

FM Transmission Limits

Audio is broadcast on the 87.5 MHz to 108.0 MHz FM band, so clarity depends on local station congestion and signal strength. The dual digital display shows real-time battery voltage, giving a quick view of the vehicle electrical system while driving.

Upgrade Context

This adapter replaces basic chargers or aux cables that lack fast charging or lossless playback. The jump is worthwhile when you need simultaneous 18 W PD and 18 W QC3.0 charging, TF card support up to 64 GB for WAV and FLAC files, and seven-colour LED backlighting in one device.

Questions about this item

Should I choose the USB-A QC 18W port or the USB-C PD 18W port for my phone?

Use the USB-C PD 18W port for phones that support Power Delivery and the USB-A QC 18W port for Quick Charge 3.0 devices; both deliver up to 18W simultaneously for a combined 36W maximum.

What does the 36W total power rating mean when both ports are used at once?

The adapter can fast-charge two phones at the same time, supplying up to 18W from each port without reducing speed on either output.

How does Bluetooth 5.0 affect call clarity and music streaming in this transmitter?

Bluetooth 5.0 gives a faster, more stable link for A2DP music streaming and the built-in CVC microphone, so hands-free calls stay clear even with road noise.
