# Choose an approach > **Note (legacy): A newer version of the Navigation SDK is available** > > This page uses v1.6.2 of the Mapbox Navigation SDK. A newer version of the SDK is available. Learn about the latest version, v2.22.2, in the [Navigation SDK documentation](https://docs.mapbox.com/android/navigation/guides/). The Mapbox **Navigation SDK**'s core logic and UI elements provide different ways to create a turn-by-turn navigation experience. Various approaches have their own benefits and limitations. This guide will walk you through the options and provide some guidance on how to get started with each. As a reminder and as explained in [the Navigation SDK overview](https://docs.mapbox.com/android/legacy/navigation/guides/#available-sdks), the core part of the Navigation SDK provides navigational logic such as route requesting and determining when the device is off-route. The UI part of the Navigation SDK provides pre-built UI elements. ## Drop-in UI If the only map in your application is used for a turn-by-turn navigation experience, Mapbox offers a more customizable approach: the **Navigation UI SDK's** `NavigationView`. **Benefits:** - Broad set of customizable options - Predefined UI elements **Limitations:** - Limited options for modifying `NavigationView` layout elements - No seamless access to the `MapView`'s instance ![A turn-by-turn navigation application built using the Mapbox Navigation SDK's NavigationView.](https://docs.mapbox.com/android/assets/ideal-img/navigation-overview-navigation-view.09c3567.480.png) ### Add the `NavigationView` The [`NavigationView`](https://docs.mapbox.com/anrdoid/navigation/v2/api/1.6.2/libnavigation-ui/-u-i/com.mapbox.navigation.ui/-navigation-view/) class extends the Android `View` class. `NavigationView` is like the Maps SDK's [`MapView`](https://docs.mapbox.com/android/maps/api/9.7.1/com/mapbox/mapboxsdk/maps/MapView.html) class in creating a map and customizing it. The difference is that the navigation functionality is already built in and does not have to be added via the core Navigation SDK. After initialization of `NavigationView`, the `startNavigation(NavigationViewOptions options)` method can be called to start the turn-by-turn navigation experience on the initialized map. > **Related content (example): [Basic Navigation UI SDK implementation](https://docs.mapbox.com/android/legacy/navigation/examples/basic-nav-ui-sdk/)** ## Collection of standalone components If you want to build a completely customizable turn-by-turn experience, you can use the core **Navigation SDK** to build standalone navigation components on top of the **Maps SDK for Android's** `MapView`. This approach may also be appropriate if you'd like to integrate components of turn-by-turn navigation into an existing mapping application. For example, you could use the Navigation SDK to request a `DirectionsRoute` and use the Maps SDK to draw a two-color gradient line that follows the same path as the `DirectionsRoute`, but you don't plan on providing turn-by-turn instructions. **Benefits:** - Completely customizable - Do Navigation on the same `MapView` that is used for other tasks **Limitations:** - No out-of-the-box solution - Layout and function need manual implementation ![A turn-by-turn navigation application built using the core Mapbox Navigation SDK and the Mapbox Maps SDK.](https://docs.mapbox.com/android/assets/ideal-img/navigation-overview-map-view.c41b96b.480.png) ### Build a collection of components The interplay of the Maps SDK's [`MapView`](https://docs.mapbox.com/android/maps/api/9.7.1/com/mapbox/mapboxsdk/maps/MapView.html) and the navigation logic that's provided by the Navigation SDK's [`MapboxNavigation`](https://docs.mapbox.com/android/navigation/v2/api/1.6.2/libnavigation-core/-core/com.mapbox.navigation.core/-mapbox-navigation/) class, creates the most customizable approach to turn-by-turn navigation experiences. This combination brings together the `MapView` class, which allows for embedding highly customizable maps, and the full flexibility of the `MapboxNavigation` class. This allows you to customize every detail of the navigation experience without having to build it completely from scratch (using [Mapbox APIs](https://docs.mapbox.com/api/) directly). - **Map**: You will need to include a `MapView` element in your project's layout XML file. You can read more about how to customize `MapView` in the [Maps SDK for Android documentation](https://docs.mapbox.com/android/maps/guides/). - **Route**: Display a route on the map (Navigation UI SDK's `NavigationMapRoute` standalone component can be used). - **Route events**: A [`RouteProgressObserver`](https://docs.mapbox.com/android/legacy/navigation/guides/route-progress/#listen-to-progress-change) can be attached, which implements callbacks related to route progress. An [`OffRouteObserver`](https://docs.mapbox.com/android/legacy/navigation/guides/off-route/) can also be attached. - **Instructions**: To include an `InstructionView` panel that displays instructions as needed along the route, you will need to include an [`InstructionView`](https://docs.mapbox.com/android/legacy/navigation/guides/manuever-instructions/) element in your project's layout XML file. This panel can also include navigation icons that show what maneuver to take next. Any icons can be used, but Mapbox offers an [open set of icons](https://github.com/mapbox/directions-icons). - **Route summary**: Most turn-by-turn navigation experiences also include a way to view a list of all instructions along with a summary of the distance and time required to complete the route (Navigation UI SDK's `SummaryBottomSheet` standalone component can be used). - **Feedback**: You should include a mechanism for users to provide feedback (Navigation UI SDK's `FeedbackButton` and `FeedbackBottomSheet` standalone components can be used). - **Voice**: You should include instructions for the `NavigationSpeechPlayer` to read out loud (Navigation UI SDK's `VoiceInstructions` can be used). > **Related content (example): [Basic Navigation + Maps SDK integration](https://docs.mapbox.com/android/legacy/navigation/examples/basic-nav-sdk-only/)** > > Shows how to combine the Maps SDK with only the Navigation SDK and no Navigation UI SDK code of any kind.
