0.2.22 — public preview
Install on the car, not the iPhone. No jailbreak, dongle, Mac, account or authentication server is required for use. Core CarPlay does not require ADB; optional dashboard, battery, wheel-speed and parked-video features do. Your head unit must permit APK installation. The APK supports Android 7.0+ (API 24); on Android 7.0–8.1, wired CarPlay is confirmed on one car and wireless is not yet confirmed on a vehicle. Wireless supports Wi-Fi Direct, the car’s existing hotspot or Existing Wi-Fi / Same LAN. Android 7.0–9 Wi-Fi Direct uses a firmware-dependent legacy path with generated group credentials and unverified requested frequency; see Android 9 Wi-Fi Direct. Android 10+ verifies its negotiated group frequency.
- Wired USB and wireless CarPlay with local authentication.
- BYD HUD navigation with arrows, distance and street names on verified firmware.
- Car hotspot support, improved audio buffering and saved receive diagnostics.
- Automatic address discovery, fixed-channel Wi-Fi fallbacks and successful-configuration memory.
- Icon/text size, resolution and frame rate; applying a display change reconnects CarPlay.
- Local diagnostic export. Reports are sent only if you choose to share them.
- Separate installation alongside DiAuto. Run one projection app at a time.
This is not an Apple-certified product. The APK bundles an experimental accessory identity recovered from public Carlinkit firmware, not a newly provisioned MFi identity for DiPlay. A bundled private key is extractable. Acceptance after future iOS updates, reliability across head units and suitability of that identity for general distribution are unresolved. This release invites community testing; it is not a guarantee of universal compatibility.
Earlier releases were tested on the development DiLink5.1 car: live windshield guidance and street names work, Car hotspot now starts CarPlay, and Wi-Fi Direct performance is substantially improved. Audio underrun recovery is improved in 0.2.15; remaining cutouts need current diagnostic reports. The 0.2.16 software Opus microphone fallback was accepted on a BOS Mini A1 head unit (Android 9) with an iPhone 12 on iOS 27. The floating-map test build was installed on the development DiLink 5.1 car; feedback led to the pinch corrections in 0.2.9. Earlier wheel-speed and video contributions were tested on a BYD Tang with DiLink 5.0 and an iPhone 15 Pro on iOS 27; wheel-speed dead reckoning in tunnels remains unverified. Broader head-unit and iOS compatibility is not guaranteed. The HUD firmware scope and cleanup limits are documented in BYD navigation.
What’s new in 0.2.22
- Wireless CarPlay over the car hotspot connects again on BYD DiLink 3.0 and 4.0 head units where 0.2.21 stayed on "Opening CarPlay"; the Hotspot interface (optional) workaround can be cleared.
- Music plays at the iPhone's speed over Wi-Fi again, from the first second of every song, without the 0.2.21 speed-up and stutter.
- Over USB, WeChat voice messages, Voice Memos and dictation record your voice instead of silence.
- Wired CarPlay connects on the first attempt after a replug, and the CarPlay screen and Home say why a connection failed and what to change.
- DiPlay is available in Korean and Turkish.
- New options, off by default: keep CarPlay in the launcher card, navigation prompts that ask for audio focus, calls at the call's own rate, a full-screen DiLink 3.0 dashboard map and the dashboard map on the Denza N9.
See 0.2.22 release notes and validation for contribution links and remaining physical tests. General stutter, calls/Siri, decoder and model-specific reports still need current-device evidence. 0.2.21 notes remain available as historical guidance.
If a problem remains, reproduce it on 0.2.22, then use Settings → Diagnostics → Save diagnostic report. Android 10+ normally saves to Downloads/DiPlay; Android 7.0–9 asks for storage access and saves there too. If unavailable, use View report or Share from the confirmation, which identifies external/private fallback storage. Review the .txt and attach it as a file to a matching existing issue, or create one. Include vehicle/head-unit model, exact firmware and Android/DiLink, phone/iOS, connection backend, relevant settings, steps and failure time. Reports are shared only when you choose; never post your hotspot password.
Documentation
Existing Wi-Fi / Same LAN keeps the iPhone and head unit
on an external router. See the guide for setup, build requirements and the
BYD DiLink 4.0 / Android 10 clean-install validation result.
