Bluetooth 5.1 Car Audio Adapter

This compact adapter adds Bluetooth 5.1 connectivity to a vehicle sound system.

Drivers wanting simple wireless audio

Questions about this item

Does this receiver transmitter adapter need a separate power supply or car kit to work?

No external power supply is required; the unit is plug-and-play and draws what it needs from the car speaker connection it pairs with.

Will this adapter stay connected if I pair it with an older phone or car stereo?

It uses Bluetooth 5.1, which maintains backward compatibility so older Bluetooth devices can still pair and stream audio.

How can I confirm the adapter is transmitting and receiving correctly after I plug it in?

Pair a phone, play music and make a test call; sound should come through the car speaker and the built-in microphone should pick up your voice clearly.
