# Instrument Cluster

Navigation SDK UX Framework comes with a built-in Instrument Cluster support for Android Automotive devices. You have to explicitly enable it when initializing the UX Framework:

```kotlin
Dash.init(
   applicationContext = applicationContext,
   accessToken = getString(R.string.mapbox_access_token)
) {
    cluster {
        enabled = true
    }
}
```

The framework also includes an Android activity that can be rendered on the Instrument Cluster. To use the activity, it is enough to add the following dependency to your project:

```Kotlin
// build.gradle.kts
dependencies {
   implementation("com.mapbox.navigationux:cluster:1.28.0")
}
```

## Customization

If necessary, you can replace the map styles with your own through the configuration object like this:

```kotlin
Dash.init(
   applicationContext = applicationContext,
   accessToken = getString(R.string.mapbox_access_token)
) {
    cluster {
        enabled = true
        dayStyleUri = <day_style_uri>
        nightStyleUri = <night_style_uri>
        satelliteStyleUri = <satellite_style_uri>
        map3dStyleUri = <map_3D_style_uri>
    }
}
```

If the prebuilt activity doesn't suit your needs, you can implement your own. The activity has to be marked with category `android.car.cluster.NAVIGATION`:

```xml
<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.car.cluster.NAVIGATION" />
</intent-filter>
```
