Introduction

Mobile navigation allows map partners to easily display their maps as well as present visual and audio turn-by-turn prompts on the head unit.

Navigation apps have different behavior on the head unit than normal applications. The main differences are:

• Navigation apps don't use base screen templates. Their main view is the video stream sent from the device.
• Navigation apps can send audio via a binary stream. This will attenuate the current audio source and should be used for navigation commands.
• Navigation apps can receive touch events from the video stream.

Configuring a Navigation App

The basic connection setup is similar for all apps. Please follow the Integration Basics guide for more information.

In order to create a navigation app an appType of SDLAppHMITypeNavigation must be set in the SDLManager's SDLLifecycleConfiguration.

The second difference is that a SDLStreamingMediaConfiguration must be created and passed to the SDLConfiguration. A property called securityManagers must be set if connecting to a version of Core that requires secure video and audio streaming. This property requires an array of classes of security managers, which will conform to the SDLSecurityType protocol. These security libraries are provided by the OEMs themselves, and will only work for that OEM. There is no general catch-all security library.

Objective-C

SDLLifecycleConfiguration* lifecycleConfig = [SDLLifecycleConfiguration defaultConfigurationWithAppName:@"<#App Name#>" fullAppId:@"<#App Id#>"];
lifecycleConfig.appType = SDLAppHMITypeNavigation;

SDLStreamingMediaConfiguration *streamingConfig = [SDLStreamingMediaConfiguration secureConfigurationWithSecurityManagers:@[OEMSecurityManager.class]];
SDLConfiguration *config = [SDLConfiguration configurationWithLifecycle:lifecycleConfig lockScreen:[SDLLockScreenConfiguration enabledConfiguration] logging:[SDLLogConfiguration defaultConfiguration] streamingMedia:streamingConfig fileManager:[SDLFileManagerConfiguration defaultConfiguration]];

Swift

let lifecycleConfig = SDLLifecycleConfiguration(appName: "<#App Name#>", fullAppId: "<#App Id#>")
lifecycleConfig.appType = .navigation

let streamingConfig = SDLStreamingMediaConfiguration(securityManagers: [OEMSecurityManager.self])
let config = SDLConfiguration(lifecycle: lifecycleConfig, lockScreen: .enabled(), logging: .default(), streamingMedia: streamingConfig, fileManager: .default())

Must

When compiling your app for production, make sure to include all possible OEM security managers that you wish to support.

Keyboard Input

To present a keyboard (such as for searching for navigation destinations), you should use the SDLScreenManager's keyboard presentation feature. For more information, see the Popup Menus and Keyboards guide.
