When troubleshooting Android Auto connectivity issues, it's important to consider both the smartphone and the car's infotainment system, as the latter also runs on software that may need updating. Google recommends restarting the infotainment system and checking for firmware updates, especially for aftermarket units. Automakers are releasing updates to improve Android Auto performance, such as Hyundai's February 2026 update for ccNC-equipped vehicles in Europe, which enhanced wireless connectivity and reconnection capabilities. The method for installing updates varies by manufacturer, with some allowing direct downloads via Wi-Fi and others requiring a USB drive or dealer assistance. A firmware update may not resolve all Android Auto issues, particularly if problems arise after a phone or Android Auto update. It's advisable to check Google's Known Issues page for specific models before updating the car's software. Compatibility should be verified, and Android Auto must be enabled in the infotainment system. Updating the car's software is a troubleshooting step, not a guaranteed fix, and firmware updates cannot enable Android Auto on unsupported hardware.
