Fcc Plugin is a free utility and tool software developed by SpeedFire for Android devices. This plugin is specifically designed for FlyAudio G8 and G9 head units and allows users to add custom functionality to the FlyAudio's steering wheel Speech button. With this plugin, users can launch apps, start Google Voice, and cycle through apps using the Speech button on their car's steering wheel.

It is important to note that this plugin only works with the main Fcc Car Launcher app installed, which is available for download on the Google Play Store. This is not a standalone app and requires the FlyAudio G8 or G9 head unit to function properly. Additionally, users need to assign the "Speech" function to a selected steering wheel button using FlyAudio's built-in settings.
