Why Xiaomi could replace the USB-flash drive
Modern Xiaomi smartphones are able not only to store thousands of songs, but also to emulate. USB-This is a solution that's relevant if your car supports music playback from the car. USB, But you don't want to use a separate flash drive or it has a broken plug, and the main advantage is that you can update playlists directly from your smartphone without reconnecting the physical media.
However, not all Xiaomi models and not all car radios support this functionality out of the box. Depending on the version of MIUI, the type of connection (USB-A, USB-C, wireless CarPlay) and the firmware of the car head unit, additional settings may be required. In this article, we will analyze all possible scenarios, from basic connection to solving rare errors.
What Xiaomi models support the regime USB-storage
Emulation function USB-storage device (also known as USB Mass Storage or MTP/PTP) Available on most Xiaomi smartphones, but with reservations:
- π± Flagship models (Xiaomi) 13/14, Redmi K60, POCO F5): Supports all data transmission modes, including MTP and PTP. It can be used for both music and video.
- π± Mid-size segment (Redmi Note 12, POCO X5, Xiaomi 12 Lite: Usually only work in mode MTP, This can limit compatibility with older radios.
- π± Budget models (Redmi) A2, POCO C55): often deprived of regime USB Mass Storage, but can work through MTP Android Auto-based.
Important: If your stereo requires the FAT32 format (not exFAT or NTFS), then the smartphone file system must be compatible. On Xiaomi with MIUI 14+, this is set up manually via Settings β Storage β Format as internal memory (but that will delete all data!).
Preparing the Xiaomi smartphone for connection
Before you connect your phone to the tape recorder, follow the following steps:
Download music to the Music or Media folder on your phone |
Turn off USB Debugging mode in Settings β About Phone β MIUI version (7 times tap, then return to Additional Settings β For Developers)|
Activate File Transfer (MTP) mode in the notification when you connect to USB|
Check format compatibility (the magnet may not support.flac or.wav)
-->
Pay special attention to audio file formats. Most car radios support:
| Format | Compatibility | Quality. | Notes |
|---|---|---|---|
| .mp3 | 99% | Average. | The Best Choice for Compatibility |
| .wma | 80% | Low. | It is supported by old tape recorders. |
| .aac | 70% | High. | It may not be reproduced on budget models. |
| .flac | 30% | Maximum. | Requires a Hi-Res-enabled magneto |
| .ogg | 10% | High. | It is not supported in practice. |
If your radio canβt see files, try converting music to.mp3 at 192-320 kbps bitrate through apps like MediaHuman Audio Converter or Freemake. Xiaomi can use MIUI File Manager with a built-in converter (not available on all models).

If the tape can't see the music folder, create a USBMusic folder on the phone in the root directory and transfer the files there. Some head devices only look for media in folders with certain names.
How to connect Xiaomi to the tape recorder via USB
There are three main methods of connection, and their choice depends on the capabilities of your radio:
1. Direct connection in MTP/PTP mode
The easiest method that works on 80% of the magneto USB-port:
- Connect your phone to the tape recorder via a USB-A β USB-C cable (or Micro-USB if you have an older model).
- On the smartphone screen, select File Transfer (MTP) mode.
- In the radio menu, select the USB or Media Device source.
If the radio canβt see the phone, try:
- π Reboot both devices.
- π Use a different cable (some cables are only for charging).
- π± Set the regimen on PTP instead MTP (In some cases, it helps).
2. Mode USB-Storage (Mass Storage)
This method only works on smartphones with unlocked bootloader and custom firmware (like LineageOS), which is not available on standard MIUI, and if your radio requires a USB Mass Storage, you will have to:
- Unlock the bootloader through the Mi Unlock Tool.
- Install custom recovery (TWRP).
- Switch the USB Mass Storage Enabler module through Magisk.
β οΈ Note: this method voids the warranty and may result in data loss. Use it only if other methods do not work.
3. Connect via Android Auto (Wireless or USB)
If your radio supports Android Auto, you can stream music through apps (Spotify, YouTube Music, MIUI Music).
- Connect your phone to the radio via USB (or Wi-Fi if you support Wireless Android Auto).
- Run Android Auto on your phone.
- Select an application for playing music.
The advantage of this method is access to streaming and playlists without first downloading files, but it requires stable connection and can slow down on weak radios.

Solving common problems
Even with the right setup, errors can occur, and here are the most common ones and ways to fix them:
1.The magneto doesn't see the Xiaomi phone
Causes and solutions:
- π Faulty cable: Try a cable from a phone kit or a certified cable USB-IF.
- π± Wrong regime. USB: on the phone when connecting, select File Transfer (MTP), Not just charging.
- π§ Outdated firmware of the tape recorder: update the software of the head device through the official website of the manufacturer.
- π« Lockdown USB Port: Some radios block smartphone connection due to security policies (especially in rental machines).
2. the music is played with interference or interrupted
This may be related to:
- π Low bitrate files: Convert music to.mp3 320 kbps.
- β‘ Lack of power: connect your phone to charge in the machine (some tapes donβt provide enough current through the machine) USB).
- πΆ Interference from other devices: turn off Bluetooth and Wi-Fi on your phone.
3.The magnetola sees the phone but doesn't see the music
The problem is usually:
- π Wrong folder structure: Create a Music folder in the phoneβs root directory.

- π Incompatible tags: Some tape recorders donβt read Cyrillic files in title or tags (use this). MP3Tag name-name).
π‘
If the stereo doesn't see music but sees other files (photos, documents), the problem is exactly in the audio format or folder structure. Start by converting files to.mp3 and checking folder names.
Alternative ways to listen to music in the car
If the USB connection doesnβt work or isnβt comfortable, consider alternatives:
- π§ Bluetooth: Most of Xiaomi supports A2DP The downside is the possible delays and the low quality on cheap tapes.
- π‘ FM-Transmitter: Devices like Nulaxy KM18 transmitting sound from the phone to the tape recorder through FM-It's good for old cars without radio. USB.
- π Aux cable (3.5 mm): if the car has an entrance AUX, You can plug your phone directly in. The new Xiaomi without a connector will require an adapter. USB-C β 3.5 mm.
- π± CarPlay/Android Auto over Wi-Fi: If the tape recorder supports wireless connectivity, you can stream music without cables.
Comparison of methods for convenience and quality:
| Method | Sound quality | Convenience | Compatibility | Additional expenses |
|---|---|---|---|---|
| USB (MTP) | βββββ | ββββ | 80% | No. |
| Bluetooth | βββ | βββββ | 95% | No. |
| FM-transmitter | ββ | ββ | 90% | 1000β3000 β½ |

| Android Auto (USB/Wi-Fi) | ββββ | βββββ | 60% | No. |
For maximum sound quality, we recommend combining methods: for example, using USB for local files and Bluetooth for streaming.
Optimizing sound when playing via USB
To make the music sound better, adjust the uniform output signal:
- On your phone, turn off all sound effects: Settings β Sound and vibration β Sound effects β Turn everything off
- In the tape, activate Flat or Pure Audio mode (if any).
- Use uniform volume for all tracks (in the MIUI Music is a function of sound normalization).
If your tape recorder supports EQ-settings, try the following presets for different genres:
- πΈ Rock/Metal: Increase low (60β120 Hz) and high (8β12 kHz) frequencies.
- π€ Vocals/Pop: Raise the average frequencies (1-4 kHz) for clarity of voice.
- π» Classics/Jazz: Use Linear EQ or slight boost at 250 Hz and 10 kHz.
β οΈ Warning: Don't increase the bass (60-200 Hz) too much - this can cause the sound distortion on the cheap speakers of the machine. +3 dB.
