DiAuto 0.3.1 — Android Auto for BYD DiLink

First public release of DiAuto, an independent Open Headunit fork focused on BYD DiLink.

Download page and installation guide — English · العربية · Русский · Español · 简体中文

Install the APK on the car, then use your compatible Android phone's built-in Android
Auto support. No additional phone companion app, dongle, external hardware, root or
firmware modification is needed. An Android phone is required; this is not Apple CarPlay.

Included

  • Native wireless Android Auto and wired USB support.
  • Redesigned home, settings options, toggles, pickers and dialogs.
  • Music-through-car-Bluetooth mode to avoid competing media audio focus.
  • Matching non-DFS 5 GHz channel preference when the head unit is already connected to
    Wi-Fi; automatic fallback on unsupported channels or failed creation.
  • Bounded SurfaceView frame pacing and full-screen 1080p touch alignment.

Compatibility and validation

Tested on BYD DiLink 5.1 running Android 13 with wireless and physical USB connections.
576 unit tests pass; optimized release assembly and release vital lint pass. The final
public signed APK was installed and smoke-tested on an Android emulator.

Wireless map-drag samples improved from 34–35 FPS to 47–58 FPS after channel alignment
in the tested setup. Performance varies; one later music-playback sample still had a
103 ms stall. The tested display reports approximately 58 Hz. Constant 60 FPS is not
promised. Other head units, firmware versions and long-term thermal behavior are not verified.

Install / update

Download DiAuto-v0.3.1.apk below and follow the installation guide.
Some DiLink firmware requires the manual Static BSSID step documented there.

This first public release uses a dedicated signing key. Private development previews
and upstream builds may have a different signature and cannot update in place. Export
your settings before uninstalling a conflicting build; uninstalling removes local data.
Future public releases will use this release key.
