How to Add Android Auto to Android Head Unit (2026 Guide)

Does Your Android Head Unit Support Android Auto Natively?

The first question is whether your unit has native Android Auto support. Here's how to check:

• Look in Settings → Apps — if "Android Auto" appears in the app list, your unit supports it natively.
• Check the firmware version — units running Android 10 or higher are most likely to have it. Units on Android 8 or 9 usually need a workaround.
• Check the manufacturer's spec page — ATOTO, Pumpkin, Eonon, and Joying all publish this. A "Google GMS certified" label on the box usually means native Android Auto is included.

If your unit has native Android Auto, you just need to plug in your phone with a data-rated USB cable, open Android Auto on your phone, and follow the prompts. Skip to the connection troubleshooting section if it's not connecting.

Method 1 — Sideload the Official Android Auto APK

If your unit doesn't have Android Auto pre-installed but runs Android 9+, you can sideload it:

1. 1Enable unknown sources — go to Settings → Security → Unknown Sources → enable for your file manager app.
2. 2Download the Android Auto APK — search APKMirror for "Android Auto" and download the latest stable version.
3. 3Transfer to your head unit — copy the APK to a USB drive, plug it in, and open it with your file manager.
4. 4Install it — tap the APK file, allow the install. It will appear in your app drawer.
5. 5Connect your phone — plug in via USB data cable, open Android Auto on your phone, and follow the setup wizard.

Method 2 — Use AutoKit (Recommended for Older Units)

AutoKit is a paid app (~$5 one-time) that brings Android Auto and CarPlay to any Android head unit running Android 5+. It's the most reliable solution for older units.

Setup steps:

1. 1Install AutoKit from the Google Play Store (or sideload the APK if Play Store isn't available — see our app installation guide).
2. 2Launch AutoKit and grant all permissions.
3. 3For wired Android Auto: plug your phone into the head unit's USB data port using a data-rated cable. AutoKit will detect it automatically.
4. 4For wireless Android Auto: make sure your phone supports wireless Android Auto (Pixel 6+, Samsung S10+ on Android 11+), then connect your phone to the head unit's WiFi hotspot or use a shared 5GHz WiFi network.
5. 5Set AutoKit as the default home app if you want it to launch automatically on startup.

Method 3 — Use CarStream (Free Open-Source Option)

CarStream is a free, open-source alternative to AutoKit. It works on Android 6+ and supports wired Android Auto only (no wireless). Good for units where you just want a no-cost solution.

1. 1Download CarStream from GitHub (search "CarStream APK GitHub").
2. 2Sideload and install via your file manager.
3. 3Grant all requested permissions.
4. 4Connect your phone via USB data cable.
5. 5CarStream will launch Android Auto on the head unit screen automatically.

Method 4 — Android Auto Wireless Dongle

If your phone supports wireless Android Auto but your head unit only has USB, a wireless Android Auto dongle (like the AAWireless or Motorola MA1) solves the gap:

1. 1Plug the dongle into your head unit's USB port.
2. 2Pair your phone with the dongle via Bluetooth (one-time setup).
3. 3After that, Android Auto connects automatically whenever you get in the car — no cable needed.

These dongles typically cost $40–$80 and work with any head unit that already supports wired Android Auto. Not needed if you're using AutoKit's wireless feature.

Troubleshooting — Android Auto Won't Connect

For USB connection issues specifically, see our USB not working guide. If your head unit can't find the Android Auto app at all, see our app not working guide for app installation troubleshooting.

Get More Out of Your Android Head Unit

Once Android Auto is running, you're only using a fraction of what your head unit can do. The Complete Android Head Unit Bundle includes our full setup guide, launcher configs, and troubleshooting guide — everything you need to configure your unit from scratch, fix common issues, and make the interface actually usable.

If you're still setting up your unit and haven't done the full configuration, start with our Android Head Unit Master Setup Guide — it walks through launcher setup, connectivity, GPS, and app installation in one place.
