Users can manually update Android Auto through the Play Store
Because Android Auto ships as a regular Play Store app rather than a system component, it normally updates automatically in the background, but that process can stall if a phone lacks Wi-Fi access or auto-update settings are disabled. Users can check their version by searching for Android Auto in the Play Store, where an Uninstall button confirms they already have the latest release, or an Update button lets them install it manually. Devices need Android 9.0 or later, released in 2018, to receive current updates.
