Headunit Receiver emulator for Android Auto.

How to use the app?

USB Mode

Plug in the USB  to your device (in case of tablet use an OTG cable), when prompted make sure you allow HUR to be the default app for the action and you check the always box.
If you are running the app on a device with Android 7.0 or higher, you might need to pull down the notification bar and select the connected USB device before the app starts (this is device dependent)


Wifi
Install WiFi Launcher app on the phone!In WiFi Launcher select the cars BT, so app starts automaticallyEnable hotspot option in WiFi Launcher, connect your car's unit to the phones hotspot and open HeadUnit Reloaded (you can reverse the hotspot / client roles as well if you wish)


Self Mode (when Android Auto and HUR are running on the same device)
- Open HUR and press Self-mode (make sure you have Android Auto installed on the device you are trying to achieve this) 


FAQ / Troubleshoot

 All I get is a black screen 
 - If you are using an Android powered headunit (Joying, Xtrons, etc) look for a setting on your device which allows Video Playback during drive
 - Try changing HUR settings and enable Software decoding


Compatible with: Joying, Eonon, Grom Vline, Xtrons, PX5 and PX3 units, A-Sure, RK3188 units, RK3066 units, Avin and other Android powered head units.

The original idea was developed by the late MICHAEL READ.

Turn your tablet or Android powered unit into a full blow Android Auto headunit.
