Your car stereo, bookshelf speaker or TV can stream from your phone without a new head unit or a cable. The GR11 is a small metal adapter that works as a receiver or transmitter, set by one slide switch. Calls come through the speakers you already have.
Bluetooth 5.3 2-in-1 transmitter and receiver that turns any wired audio device into a wireless one
Solves
- Old car stereo lacks Bluetooth
- Wired-only speakers or amplifiers
- Computer or TV without wireless audio output
- Hands-free calls in the car without a built-in kit
Your Old Stereo Goes Wireless in One Plug-In
Music, navigation and hands-free calls from your phone, through the car stereo or speakers you already own. One small metal unit, one switch, and no new head unit to install.
A Metal Body Built for Daily Use
Two Modes, One Switch
A single slide sets the unit to transmit or receive. Slide to RX to play phone audio through a stereo, speaker or amplifier. Slide to TX to send audio from a TV or computer to wireless headphones. The LED display and one-key switch make the mode easy to confirm before you pair.
Built for Hands-Free Calls
The built-in microphone lets you answer calls through the speakers you already have. Nothing extra to mount or wire. Keep the mic facing you and unobstructed, and the other side hears you clearly over road noise.
Solid Metal Housing
The brushed silver aluminum body and textured black grip panel feel solid in the hand. The metal shell gives the unit a finished, premium look that sits well beside a dashboard or a desk setup.
Slide the Switch and Pair
- 1Pick the mode
Slide the TX/RX switch to RX if the audio should go into a stereo, speaker or amplifier. Slide it to TX if the audio comes from a TV or computer and should go to headphones.
- 2Plug into the 3.5mm jack
Connect the adapter to the AUX input of your stereo or speaker in RX mode, or to the audio output of your TV or PC in TX mode.
- 3Check the LED display
The LED display shows the current state. Confirm the mode before you start pairing so the device appears in the right list.
- 4Pair your phone or headphones
Turn on Bluetooth on your phone or headphones and select the GR11 from the list. In RX mode, a second device can connect at the same time.
Good Sound, No Way In
The Stereo Still Works. It Just Cannot Connect.
A cable from the glovebox, a phone wedged in the cup holder, and a podcast that cuts out at the first junction. Older stereos were built for radio and cassettes, so every trip starts with a small negotiation. You either give up on music or hold the phone to your ear while you drive.
One Small Unit Changes the Connection
The GR11 plugs into the 3.5mm input your stereo already has and turns it into a Bluetooth 5.3 receiver. Set the TX/RX switch to RX and pair your phone. You skip the head unit, the dashboard work and the hundreds of dollars that usually come with it.
Calls and Music, Without the Cable
Navigation prompts come through the speakers, a call comes in and the built-in microphone picks up your voice from the dash. Both hands stay on the wheel and the phone stays in your pocket. The drive feels like it always should have.
What to Expect
- First usePaired and playing
Set the switch to the right mode, connect your phone, and play audio through the old speakers. Most setups take a few minutes the first time.
- 3 usesSwitching feels natural
After a few drives or sessions, the mode switch and pairing become routine. You will know which mode to choose before you plug in.
- 30 daysPart of the routine
Calls, navigation and music run through the existing system every day. The unit stays in place without needing attention.

Questions and answers
Will it work with my old car stereo if it only has an AUX input?
w
Wanelo · seller
Yes. Any stereo with a 3.5mm AUX input can take the GR11 in RX mode. Plug the adapter into the AUX jack, slide the switch to RX, and pair your phone. If your stereo has no AUX input at all, this adapter cannot connect to it directly. Our bluetooth for car audio range covers other routes.
Can I use it to send TV or PC audio to wireless headphones?
w
Wanelo · seller
Yes. Connect the 3.5mm output of the TV or computer to the jack, slide the switch to TX, and pair your headphones. The unit sends the audio over Bluetooth, so the TV volume can stay low while you listen privately.
How clear are calls through the built-in microphone?
w
Wanelo · seller
The microphone is built into the unit, so placement matters. Mount or place it so the mic faces you with nothing covering it. Calls come through the car speakers with the mic handling your voice, and you do not need a separate hands-free kit.
Can it connect two phones at the same time?
w
Wanelo · seller
Yes, in RX mode. The GR11 links two devices at once when it is receiving audio. Dual connection does not apply in TX mode, so set the switch to RX when you need two phones.
How do I know whether to set TX or RX mode?
w
Wanelo · seller
Use RX when the audio should go into your speakers, stereo or amplifier. Use TX when the audio comes from a TV or PC and should go to wireless headphones. The slide switch is the only setting you need to change.
Is it worth it compared with replacing the head unit?
w
Wanelo · seller
A new head unit usually costs hundreds and needs professional installation. The GR11 is one small metal unit that plugs into a jack you already have, so you keep the stereo you like and pay for only the wireless link.
