DiPlay Public Preview Brings Wired and Wireless CarPlay to Compatible Android Head Units

A public preview of DiPlay, an independent CarPlay receiver application designed for compatible Android head units with a focus on BYD vehicles, is available as a wired and wireless solution. The project provides an alternative installation option that runs directly on the car's head unit rather than the iPhone, operating independently without requiring a jailbreak, dongle, Mac, account, or authentication server.

Installation and System Requirements

• Android Compatibility: The APK supports Android 7.0+ (API 24). Core CarPlay functions do not require ADB, though optional features such as the dashboard, battery, wheel-speed integration, and parked-video support do.
• Wireless Connectivity: Wireless connections support Wi-Fi Direct, the car's existing hotspot, or an existing Wi-Fi network on the same LAN.
• BYD Focus: While the application centers primarily on BYD cars, it may operate on other brands; however, other brands remain officially unsupported without planned additions or brand-specific fixes.

Features and Updates in Recent Releases

Recent updates, including version notes for 0.2.22, detail several functional additions and fixes:

• Audio and Recording: Fixes allow music to play at normal speed over Wi-Fi from the start of every song, and resolve recording silence issues for WeChat voice messages, Voice Memos, and dictation over USB.
• Connection Reliability: Wired CarPlay is reported to connect on the first attempt after a replug, with status messages on the CarPlay screen and Home explaining connection failures.
• HUD and Dashboard Options: Verified firmware supports BYD HUD navigation arrows, distance, and street names, alongside optional settings for full-screen DiLink 3.0 dashboard maps and Denza N9 integration.
• Localization: DiPlay supports multiple languages, including English, Arabic, Russian, Ukrainian, Spanish, Simplified Chinese, Traditional Chinese (Taiwan), Japanese, Italian, Korean, and Turkish.

Licensing and Technical Limitations

This release is not an Apple-certified product. The APK bundles an experimental accessory identity recovered from public Carlinkit firmware rather than a newly provisioned MFi identity. Consequently, long-term acceptance after future iOS updates, universal reliability across head units, and the suitability of that identity for general distribution remain unresolved.

The project is based on xcertplay (GPL-3.0), while the home/settings UI and website adapt DiAuto (AGPL-3.0). Apple Inc. and BYD are not affiliated with or endorsing this project.

Verification and Troubleshooting

Users encountering issues can reproduce them on version 0.2.22 and export a local diagnostic report via Settings → Diagnostics → Save diagnostic report. Reports are stored locally and are only shared if the user chooses to send them. When reporting issues on platforms like GitHub, users are advised to include the vehicle model, exact firmware, Android/Link version, and iOS details while avoiding sharing sensitive information such as hotspot passwords.
