The method to play songs via USB port in the car is: 1. Check if the vehicle supports Baidu Carlife, and download and install Baidu Carlife on the mobile phone; 2. Connect the mobile phone to the vehicle using a USB cable and open the Carlife app on the phone; 3. Enter the Carlife interface on the phone, select USB debugging in the settings menu, enable developer options and check USB debugging; 4. At this point, the Carlife interface from the phone can be projected onto the car screen, allowing you to play songs. USB has advantages such as fast transmission speed, ease of use, hot-swappable support, flexible connection, and independent power supply. It can connect various peripherals like keyboards, mice, and large-capacity storage devices, and this interface is also widely used in smartphones.

Playing music via USB is quite simple. Just plug in the USB drive, then switch the media source to USB on the central control screen. Remember to format the USB drive as FAT32 and store songs in the root directory without too many folders. Recently, I used a 64GB drive with over a thousand MP3s, and the system read them quickly. If there's no response, try switching USB ports or restarting the infotainment system. Compared to Bluetooth, USB offers cleaner sound quality without lag, and it saves your phone's battery on long trips. I usually keep the drive plugged in when driving—it automatically resumes playback from the last song, which is super convenient. Also, it's a good idea to have a dedicated small USB drive and avoid mixing it with work files.

Most cars nowadays support playing music via USB. I usually copy my favorite songs onto a USB drive in advance, then plug it into the car's USB port to play. It's a two-step process: select USB as the media source, then browse playlists like operating a smartphone. Note that the USB drive should not exceed 128GB, and new drives should be formatted as FAT32 first. If some MP3s won't play, it might be a bitrate issue – just convert them to standard 320kbps using Format Factory. Remember to delete outdated playlists when parked to speed up loading new songs. While driving, voice commands make skipping tracks super convenient without even touching the screen.

I keep a 32G USB drive plugged in my car all year round dedicated to storing songs. Every time it's inserted into the USB port, the steering wheel media button switches to USB mode, and the central display shows the song list scroll bar. MP3 format is recommended as some cars don't support WAV. Keep partitions under 32GB for better stability, and organize by creating separate folders for pop and light music. If there's reading delay, don't panic - it's usually poor contact and just needs reinserting. Update the playlist weekly to keep it fresh. Using USB doesn't consume phone data, and the sound quality is much more stable than Bluetooth.
