The setup process is not very complex, but has a number of nuances specific to the MIUI shell.

Android Auto is optimized for one-handed use and minimizes driver distraction. It requires not only a compatible car and cable to work properly, but also the right configuration of the smartphone itself. Xiaomi device owners need to pay special attention to power saving and application permissions settings, as aggressive system optimization can interrupt the connection.

You'll need a quality USB 2.0 or 3.0 wire with data support. The length of the cable also matters: too long wires (more than 2 meters) can cause signal loss.

The car itself must also support Android Auto. This is usually found in the manual to the tape recorder or on the official website of the car manufacturer.

You also need to check autorun. In the same app settings menu, find Android Auto and make sure the Autorun switch is activated. Without this permission, the system may not start the service when you connect to the machine if the application has been completely closed by the user.
