# INSetAudioSourceInCarIntentHandling

The handler interface for changing a vehicle’s audio source.

## Declaration

```swift
protocol INSetAudioSourceInCarIntentHandling : NSObjectProtocol
```

## Overview

Overview Automotive venders can support the INSetAudioSourceInCarIntentHandling protocol in an Intents extension that they ship with their automotive apps. Use the methods of this protocol to resolve, confirm, and handle requests to change the vehicle’s current audio source. Your extension should be able to communicate with the vehicle and make the necessary audio changes. Siri delivers an INSetAudioSourceInCarIntent object to your handler when the user asks to change the audio source. The provided intent object contains information that you use to determine the new audio source and to make the change.
