Your older car can stream music and take hands-free calls without a new stereo. This brushed metal receiver plugs into the AUX port you already have, with Bluetooth 5.0 and a built-in mic. Pair it once and the commute runs on your phone.
Turn any car's AUX port into a wireless Bluetooth audio input for HiFi sound and hands-free calls
- No Bluetooth in older car stereo
- Wired phone connection hassle
- Hands-free calling without built-in car Bluetooth
Wireless music and calls for any car with AUX
Your stereo still works, but your phone needs a cable to reach it. This receiver plugs into the AUX port you already have, so your music and calls stream wirelessly from the first drive.
Bluetooth and hands-free calling for your current stereo

Bluetooth 5.0 audio for your stereo
Bluetooth 5.0 connects your phone to the receiver, and the receiver feeds the audio into the car through the AUX input your stereo already has. Pair it once and the phone reconnects on its own for the rest of your drives.

Hands-free calls from the wheel
A built-in microphone sits on the receiver, so calls run through the car speakers and you never pick up the phone. Speak at a normal volume and keep your eyes on the road.

Brushed metal, compact build
The housing is brushed metal, so it feels solid in the hand and does not look like a cheap plastic plug. The body is small enough to stay in the port and sits close to the dash instead of hanging out like a loose cable.
Connected in three steps, no tools
- 1Plug the AUX cable into the car
Push the coiled 3.5mm plug fully into your car's AUX port until it sits firmly.
- 2Power the receiver over USB
Plug the USB-A body into a USB port in the car. Use a port that stays on while you drive.
- 3Pair your phone
Turn on Bluetooth on your phone, select the receiver, and choose it as the audio output. Set the phone to about three-quarters volume before you start the drive.

Coiled cable that plugs into the car's AUX port
Your stereo was never the problem
The cable that never stays put
Most drives start the same way. You dig out a short AUX cable, run it from the phone to the dash, and then spend the trip watching it slide off the seat. A wired phone ties you to one spot, and a call that comes in mid-drive means either ignoring it or reaching for the phone at a red light.
The port you already have
Your car already has the input it needs. The AUX port that has sat unused since your phone stopped using a headphone jack is enough, along with a USB port for power. Plug the receiver into aux input bluetooth adapter form, pair it once, and the stereo becomes a wireless input without any new hardware in the dash.
A quieter, hands-free drive
With the receiver in place, music and podcasts come from your phone through the speakers you already own. When a call arrives, the built-in microphone picks up your voice in the cabin, so you can talk while both hands stay on the wheel. The commute stops being a cable problem and goes back to being a drive.

Questions and answers
You need an AUX input (3.5mm) for the audio and a USB-A port to power the receiver. Most cars from the mid-2000s on have one or both. If your stereo has an AUX jack but no USB, the receiver will not power up, so check both before you buy.
Yes, as long as the stereo has a 3.5mm AUX input. The receiver does not replace the head unit. It turns the existing AUX jack into a wireless source, so your stereo stays exactly as it is.
Calls come through clearly. Music depends on your phone volume and your stereo. Set the phone to about three-quarters volume and adjust the car stereo from there, because a maxed-out phone pushes the signal into distortion. A factory Bluetooth system will still sound a step ahead, but this costs far less than a head-unit replacement.
Yes. The built-in microphone picks up your voice in the cabin, so you can talk through the car speakers without holding the phone. It is built for calls on the drive, not studio-grade recording.
No tools are needed. Push the 3.5mm plug into the AUX port, plug the USB-A body into a USB port, then pair your phone over Bluetooth 5.0. The first pairing takes a few minutes, and after that the phone reconnects on its own.
