BYD Japan — アプリのサイドロードガイド

日本向け BYD ヘッドユニット用ガイド。日本は DiLink のオンライン APK 認証地域として扱われ、ローカルパスワード地域とは動作が異なります。

最初に IVI の完全なバージョンを確認してください。 13.1.32 / 13.1.33 / 51.x の firmware を混在させないでください。
Firmware check. Installation method varies by firmware, chipset and vehicle. Check Settings → System → Version details and note the full version, such as 13.1.33.xxxxxxx.x or 13.1.32.xxxxxxx.x, then look up the matching method. This guide may not cover every combination.

INSTALLATION METHODS

USB — Application Installation {code}

日本向け設定は、ローカル共通パスワード方式ではなく BYD のオンライン認証を使用する構成です。

  1. 車両側で設定されている country code を確認します。
  2. Application Installation CODE フォルダーを作成します。
  3. APK をコピーしてデータ USB ポートに接続します。
  4. QR/クラウド認証が表示された場合は BYD 側の承認フローに従います。

日本向けに全 firmware で共通するオフラインパスワードは確認されていません。

Japan verification backend

解析された AftermarketInstallTool は日本の認証先として apr-jp.byd.auto を使用します。APK の承認結果はクラウド側で決まるため、フォルダー名が正しくても任意 APK が必ず入るわけではありません。
