Android Auto Unknown Sources: Complete Sideloading Guide 2026
Any Android Auto users tried to install an app on Android Auto and could not find it. Many apps are not supported on Android Auto. The "unknown sources" setting is on your Android phone. It helps you install apps from, outside the Google Play Store on your Android phone.
For example video players, IPTV tools or advanced utilities are not supported by default on Android Auto. That is where enabling Android Auto to install apps from sources comes in.
It does this to protect users from accidentally installing harmful apps. But when you know what you are doing, enabling android auto unknown sources is completely safe and gives you a lot more flexibility with what you can run on your car screen.
This guide covers everything from enabling the setting on your phone to getting a sideloaded app actually working on Android Auto. No root access needed. No complicated tools required.
What are Android Auto Unknown Sources?
By default Android Auto only lets you use apps that Google says are okay. By default Android Auto only you use apps that Google says are okay. These apps are checked to make sure they are safe to use when you drive.
The system checks the apps for safety.
This unlocks the ability to:
- Install apps that are not on the Play Store
- Use tools that are still in development
- Access features that Google normally blocks
But keep in mind Android Auto wasn’t designed for every type of app. So not everything you install will work perfectly.
Is It Safe to Enable Unknown Sources on Android Auto?
The setting itself is not dangerous from experience. The real risk comes from the apps you install.
Pros
- You download APK files from trusted sources.
- You know what the app does.
- You avoid modified or “cracked” apps.
- Access to more apps and features.
- Customize your Android Auto experience.
- Use apps like IPTV, browsers, and video tools.
Cons

- Giving unnecessary permissions.
- Using apps that aren’t built for Android Auto.
- Apps may not be optimized for driving.
- Possible crashes or compatibility issues.

If you are new, this method can save you a lot of frustration.
Samsung phones: Settings → Biometrics and Security → Install Unknown Apps → pick your file manager → toggle on.
