Description
Open Headunit: The Ultimate Android Auto Receiver for your Tablet!
📢 IMPORTANT REBRANDING & ANDROID AUTO 17.4+ NOTICE:
NEW NAME: "Headunit Revived" is now "Open Headunit"! This is a seamless app update—all your settings, purchases, and features remain 100% intact. ANDROID AUTO 17.4+ WIRELESS & SELF-MODE NOTICE: Starting with Android Auto 17.4, wireless connections (including Wireless Helper) and Self-Mode require the Headunit Server (Port 5277) to be running on your smartphone. Without an active Headunit Server on your phone, wireless connections will fail on Android Auto 17.4+. USB connections remain fully functional.
Breathe new life into your Android tablet or car headunit by transforming it into a fully functional, modern infotainment system. Open Headunit allows you to experience Android Auto on almost any Android device—whether via USB, wirelessly, or using the innovative Self-Mode.
This project is an open-source revival of the original "Headunit" app by Mike Reid, modernized with the latest technologies and a sleek Material 3 interface.

I was using Head unit Reloaded previously, but it was always unstable and unreliable. So far Head unit Revived seems a lot more stable and easy to set up, fingers crossed it continues to work well. For reference, I'm using a Pixel 8 phone, and I have Head unit Revived installed on an Oneplus Lite Tablet. The USB mode seems to work perfectly, as does connect the tablet to my Pixel 8's wi-fi hotspot with the head unit server activated in the Pixel 8's Android Auto developer settings.

Using it mostly as a standalone Android Auto unit directly from phone. App seems to work great, apart from the streaming service randomly turning off after ~10 mins of playing. I did manage to test the USB connection with other phone, and it worked, but I did not manage to make the Wi-Fi working with or without the Wi-Fi Helper (as there is not a clear manual how to use the Wi-Fi helper, then difficult to know where is the fault)

Unable to get it to work. It connects and then does nothing. If I select To Android Auto on the tablet, it disconnects. This is with a Lenovo Tablet and Samsung S24.

Excellent for the Kindle Fire if your goal is to reboot the device. The instant you accept the connection for Wi-Fi Direct using the helper app on your phone the Kindle reboots. Both Fire 7 and Fire HD 8. Great work

Frequent disconnections. Need to connect again and again. I tried all connection methods e.g. Wi-Fi hotspot method, Wi-Fi Direct method etc. Also, I had checked all the settings including Wi-Fi and battery settings. But, the result is same i.e. frequent disconnections. Please resolve the issue.
