According to Gemini, the CN ROM Find X9s Pro fully supports Android Auto.

Can anybody validate this?

The Oppo Find X9s Pro (China ROM) officially supports Android Auto.

Historically, Chinese ROMs from Oppo and Vivo lacked the necessary system framework for Android Auto, making it impossible to use even with side-loaded Google Play Services. However, starting with the Find X8 series and continuing into the Find X9 series (released April 2026), Oppo has integrated full support for Android Auto directly into ColorOS 15.1 and 16.1.

Key Details for the China ROM

• Out-of-the-Box Support: Unlike older Chinese flagship models, the Find X9s Pro includes the underlying Google stubs required for Android Auto to function without complex workarounds or rooting.
• Google Play Services: While not pre-installed, you can easily install the Google Play Store via the Oppo App Market. Once the Play Store is active, Android Auto will work as a system-level feature.
• Connection Type: It supports both Wired and Wireless Android Auto, provided your car head unit is compatible.
