 ## Requirements and limitations
 
-An optional experimental Tesla HTTP mode creates a local virtual IPv4 address through Android's VPN API without changing the system hotspot subnet or requiring certificates. Connect the car to the server device's hotspot, enable the mode in Settings, approve VPN access, and try `http://100.96.0.1:8080/`. A custom shared-space address, HTTP port (default `8080`), and a self-managed HTTP hostname are supported. Port changes apply to all HTTP entries, including same-device preview; if a new port cannot bind, the running listener and saved configuration are retained. Hotspot routing and Tesla HTTP support require device testing; creating the interface does not prove browser reachability. See the [Tesla HTTP guide](docs/TESLA_HTTP.md) (Chinese). This mode shares WheelPlay's USB CarPlay VPN and may replace another VPN.
+An optional experimental Tesla compatibility mode uses an embedded Root routing adapter based on [VPN Hotspot](https://github.com/Mygod/VPNHotspot). A rooted Android device with `su`, `ip`, and `iptables` is required. Startup checks Root once in the background; its first settings row allows a manual retry. The mode switch, mapped HTTP/HTTPS ports, and custom access IPv4 address appear after authorization succeeds. Enable the system hotspot, connect the car, turn on the mode, and try `http://100.96.0.1/` once routing is ready. Mapped ports range from `1–1023`, defaulting to `80` / `443`, and forward only this address to the ordinary Web listeners. The adapter manages the `/32` address, scoped input/return rules, and port mappings in one transaction, with cleanup on hotspot changes and shutdown. It does not obtain Android VPN consent; wired CarPlay retains its IPv6 VPN independently. See the [Tesla compatibility guide](docs/TESLA_HTTP.md) (Chinese); Android hotspot and Tesla compatibility still need device testing.
+
+Settings → Web listeners (Web 监听) contains the HTTP port (default `8080`), a self-managed Web hostname shared by HTTP and HTTPS, and an optional HTTPS switch. No Root access is required; listener ports range from `1024–65535`. Enabling HTTPS reveals its port (default `8443`) and inline certificate types: local default, PEM, and PKCS#12. Android's file picker imports PEM chains plus private keys (including encrypted keys) or PKCS#12 (`.p12` / `.pfx`) with passwords and key-alias selection. Identities are validated and saved in private non-backup storage; failed imports retain the current certificate, and occupied ports retain the current listener. Disabling HTTPS stops TLS while retaining its settings and certificate. See [Web listener and certificate setup](docs/BROWSER_AUDIO.md).
 
 - The server device requires Android 9 or later. The car's browser must support modern web features and touch interaction.
 - The server device and car must be able to reach each other over the local network. Wireless connection compatibility depends on the devices' networking capabilities.

-在设置中开启此模式并授权本地 VPN，可尝试通过 `http://100.96.0.1:8080/` 访问。车机需要连接运行 WheelPlay 的 Android 设备热点；无需证书，也不修改系统热点网段。支持自定义共享地址、HTTP 端口（默认 `8080`）和自备 HTTP 域名。端口修改同时更新所有 HTTP 入口和本机预览；运行中绑定新端口失败时保留原端口及配置。接口创建成功不代表车机可达，热点路由及不同 Tesla 版本的 HTTP 支持仍需实机验证。此模式与有线 CarPlay 共用 VPN，可能替换其他 VPN。详见 [使用与验证说明](docs/TESLA_HTTP.md)。

+## Tesla 兼容模式（实验）
+
+内置适配 [VPN Hotspot](https://github.com/Mygod/VPNHotspot) 的 Root 路由方案，需要已 Root 且提供 `su`、`ip`、`iptables` 的 Android 设备。App 启动时后台检查一次 Root，「设置 → Tesla 兼容（实验）」第一行可手动重试；授权成功后才显示模式开关、映射 HTTP / HTTPS 端口和自定义访问 IP。开启系统热点并让车机连接、打开此模式，等待路由就绪后尝试 `http://100.96.0.1/`。映射端口范围 `1–1023`，默认 `80` / `443`，只对访问 IP 生效，转发到 Web 监听高位端口。地址、热点投递、回程与映射规则统一管理，关闭模式或停止服务时清理；普通 Web 监听不依赖 Root。Tesla 模式不申请 VPN 授权；有线 CarPlay 的 IPv6 VPN 独立保留。热点路由及 Tesla 支持仍需实机验证。详见 [使用与验证说明](docs/TESLA_HTTP.md)。
