Headunit Receiver Emulator for Android Auto

How to Use the App

Follow the steps below to effectively use the Headunit Receiver (HUR) emulator for Android Auto:

USB Mode



  • Plug the USB into your device (for tablets, use an OTG cable). When prompted, ensure you allow HUR to be the default app for the action and check the "always" box.

  • If your device is running Android 7.0 or higher, you may need to pull down the notification bar and select the connected USB device before the app starts (this is device dependent).

WiFi Mode



  1. Install the WiFi Launcher app on your phone.

  2. In WiFi Launcher, select your car's Bluetooth to start the app automatically.

  3. Enable the hotspot option in WiFi Launcher, connect your car's unit to your phone's hotspot, and then open HeadUnit Reloaded. You can also reverse the hotspot/client roles if desired.

Self Mode


This mode is used when Android Auto and HUR are running on the same device:



  • Open HUR and press Self-mode (ensure you have Android Auto installed on the device you are using).

FAQ / Troubleshoot


If you encounter issues, here are some troubleshooting tips:



  • All I get is a black screen:

    • If you are using an Android-powered head unit (e.g., Joying, Xtrons), look for a setting on your device that allows video playback while driving.

    • Try changing HUR settings and enable Software Decoding.
