When troubleshooting Android Auto issues, it's important to consider both the smartphone and the car's infotainment system. Users should check for firmware updates for their vehicle, as automakers are increasingly releasing updates to improve Android Auto performance. For example, Hyundai's February 2026 update enhanced wireless connectivity for Android Auto and Apple CarPlay. The update process varies by manufacturer, with some systems allowing direct downloads via Wi-Fi, while others may require a USB drive or dealer assistance. A firmware update is not a guaranteed fix for all Android Auto problems, and users should consult Google's Known Issues page for specific device-related problems before making changes to the car's software. Additionally, firmware updates cannot enable Android Auto on hardware that was not designed to support it.
