Hey all,

I have a Mitsubishi Delica rental car with an inbuilt Alpine head unit CV1W that supports Android Auto but when I connect my device it won't allow me to select it. It does say connected through a notification. I've tried multiple USB cables and different phones (I've got a pixel 9 pro). AA works at home without issue.

Does anyone have any thoughts as to what might be stopping it from working?

Cheers

Hey everyone,

I drive an older car and have been using my mounted phone as my Android Auto head unit for a while. While I appreciate apps like Headunit Reloaded, I kept running into bugs with its self-mode.

So, I decided to build another app, which I call HeadlessUnit.

It started as a project to satisfy my needs, but I think it’s stable enough now that I want to share it.

What it does

• Self-mode only for now (only supports projection to the device itself)

• Android Auto UI stream up to 1440p@60Hz, with H.265 encoding, and automatic aspect ratio adjustment to fit device screen

• Supports Intents, so you can integrate with automation apps (currently it supports a shut down Intent, which I used to build an Automate workflow to launch the app when I mount the phone in the car, and shut down the app when I unmount it)

• Auto day/night mode based on sunrise/sunset (requires location permission)

• A modern tech stack (Kotlin + Compose + Rust)

What’s planned

• Wireless and USB projection

• More settings options

• Expanded Intent API

How to test

I've released it for closed testing on Google Play Store, which requires testers to either be in a mailing list or a group. You can , and then .

Thanks for checking it out, I’d really love your feedback!
