问HN：无线CarPlay适配器会窃取你的数据吗？
我最近在阿里巴巴国际站上订购了许多无线Carplay适配器中的一个，它通过USB连接到汽车，将你的iPhone通过蓝牙（和/或WiFi）连接到汽车的Carplay。<p>说明书提到了一项固件升级，连接互联网的方式很有趣。当适配器连接到电源时，你可以通过WiFi和浏览器中的IP地址连接到它。现在在适配器的网页用户界面中，有一个按钮可以升级固件。但是，当适配器根本没有连接到互联网时，这个功能是如何工作的呢？<p>我了解到，适配器实际上是利用iPhone的移动网络连接来发送/接收互联网数据。我之前并不知道这甚至是可能的，而且似乎没有办法停止这种连接或被通知有活动连接（除了WiFi连接显然）。<p>现在我担心的是：当适配器在车内连接到iPhone时，是否有办法让适配器使用同样的机制，通过iPhone的移动网络将Carplay数据（消息、联系人等）发送到远程服务器？

So I recently ordered one of the many wireless Carplay dongles from Aliexpress that work via USB in your car connecting your iPhone to the car's Carplay via Bluetooth (and/or Wifi) to the USB dongle.<p>The instruction manual mentioned a firmware upgrade which had an interesting way of connecting to the internet. So when the dongle is connected to a power source you can connect to it via Wifi and an IP address in your browser. Now in the dongle's web UI, there is a button to upgrade your firmware. But how does this work when the dongle is not connected to the internet at all?<p>Well as I learned, the dongle simply uses the iPhone's mobile connection to send/receive data from the internet. I wasn't aware this is even possible and there doesn't appear to be a way to stop this or be notified of an active connection (aside from the wifi connection obv).<p>Now my concern is: when the dongle is connected to the iPhone in the car, is there a way for the dongle to use the same mechanism and send Carplay data (messages, contacts, etc) to a remote server using the iPhone's mobile connection?
