How the Device Works – Technical Explanation

  • Your phone first connects to the adaptor via Bluetooth.
  • Bluetooth handles the initial handshake.
  • The adaptor then switches to Wi-Fi for the actual CarPlay/Android Auto data transmission.
  • Dual-band Wi-Fi (2.4G & 5G) enables low latency and stable audio/video signals.
  • On future starts, the adaptor automatically reconnects as long as your phone’s Wi-Fi and Bluetooth are ON.

FAQ

MY CAR DOESN’T SHOW THE ADAPTER. WHAT DO I DO?

Possible causes:

  • Phone settings issues

Try:

  • Reset network settings
  • “Forget this device” in Bluetooth
  • Re-pair cleanly
  • Try a second phone to isolate the issue

AUDIO SOUNDS DISTORTED OR DELAYED.

  • Another Bluetooth device may be interfering
  • Reset your audio output to CarPlay
  • Turn Bluetooth OFF and ON
  • Clear apps running in the background

CARPLAY DISCONNECTS RANDOMLY.

WHAT IS THE WI-FI PASSWORD FOR THE ADAPTER?

  • 12345678 or 88888888

(Bluetooth handles pairing; Wi-Fi is used for data transfer.)

WHY DOES THE DEVICE GET WARM?

This is normal - Wireless CarPlay runs over 5GHz Wi-Fi and requires continuous real-time decoding, which generates mild heat.

DOES THIS SUPPORT SCREEN MIRRORING?

No. - It only converts wired CarPlay/Android Auto to wireless.

DOES IT WORK WITH BOTH USB-A AND USB-C?

Yes - The product includes USB-A to USB-C adaptor.

DOES THE ADAPTOR REDUCE CARPLAY FEATURES?

No.
You keep full functionality:

  • Calls + Messages
  • Music apps
  • Siri
  • Dashboard UI
  • Steering wheel controls

WILL THIS AFFECT MY CAR WARRANTY?

No. - It does not modify the car, ECU, or wiring. It's just a USB accessory.

I UPDATED MY PHONE AND NOW IT WON’T CONNECT.
