How to connect Xiaomi to the tape recorder: all ways + problem solving

Modern Xiaomi smartphones (including the Redmi and POCO lines) have become an integral part of the car multimedia system. However, connecting to the radio often raises questions: Bluetooth does not find the device, Android Auto does not start, sound is delayed. In this article, we will analyze all the current ways of connection (including hidden MIUI 14/15) functions and typical errors that interfere with stable operation.

It is important to understand that the connection algorithm depends on three factors: 1) model of the tape recorder (standard or universal, with support for Android) Auto/Apple CarPlay), 2) version MIUI on a smartphone (starting with the MIUI 12 The logic of Bluetooth has changed. A2DP), 3) cable type (original) USB-C cheap).

We tested the instructions on the Xiaomi 13 Pro, Redmi Note 12 and POCO F5 with Pioneer, Sony XAV-AX5000 and budget Chinese models – all of which work.

1. Bluetooth connection: step-by-step instruction

The most common method, but it's the one that causes the most problems, and the main mistake users make is trying to connect devices before setting up Bluetooth profiles on the tape.

2. Run a search on the tape: In the Bluetooth radio menu, select "Add device" or "Search". Xiaomi should have a notification requesting pairing.
3. Confirm the code on both devices: Usually it is 0000 or 1234. If the code does not match, reset the Bluetooth settings on the tape (in the Network Reset menu).
4. Select profiles: After pairing on the tape, activate the ticks next to: "Audio (A2DP) for music, "HFP" for calls, "AVRCP" for player control.

3. Connection via AUX: If nothing works

The AUX (3.5mm connector) is a versatile way to bring Xiaomi audio to any tape recorder, even the old model.

4 Wireless connection via Miracast (Wireless Display)

If your radio supports Miracast (or Wireless Display), you can duplicate the Xiaomi screen wirelessly, which is convenient for navigation or watching videos.

1. On the tape, activate Miracast mode (in the Settings menu → Wireless Networks → Wi-Fi screen).
2. On Xiaomi, go to Settings → Connections and Sharing → Screen Transfer.
3. Select the name of your radio from the list. Confirm the connection on both devices.
4. To reduce the latency, activate the "Game Mode" option in Miracast settings (available on MIUI 14+).

Miracast's limitations:

- Sound delay ~200-300 ms (critical for music, but tolerable for navigation)

The battery is quickly depleted (consumption of ~15-20% per hour).

Not all apps support audio transmission (for example, YouTube Music can block output).
