First, locate the USB port. Some cars have multiple USB ports that can be used for both charging and playing music. Insert your USB drive into the USB port. Then press the operation button to switch to AUX mode. Continue pressing the AUX button until music starts playing.

Playing USB music in my old car, I've tried several DIY methods that work quite well. The simplest is using an FM transmitter: buy one with a USB port, plug it into the cigarette lighter socket, and insert the USB drive into the transmitter; then turn on the car radio and tune it to the transmitter's specified frequency, such as 88.1MHz. It's quick to install and costs only a few dozen dollars. If the car has a cigarette lighter, you can also charge your devices simultaneously. However, the signal can sometimes be interfered with, such as being unclear in urban areas. Another method is to check the car's AUX input: if the radio has a 3.5mm jack, buy a USB card reader to plug in the USB drive, then connect it with an AUX cable to play music; or directly use an MP3 player with an AUX port. Lastly, consider upgrading: install a new car stereo with USB functionality, which, although costing a few hundred dollars, offers better sound quality and eliminates hassle. In any case, try the cheaper options first—they're safe and hassle-free.

For our older cars, if you want to play songs from a USB drive, I've found the most hassle-free method is to buy a small device. An FM transmitter does the trick: plug it into the cigarette lighter, insert the USB drive into it, and tune your radio to the specified frequency, say around 90.0, to enjoy your music. It's easy to operate, requires no wiring modifications, and is very convenient. If you're not satisfied with the sound quality, check if your radio has an AUX port; if it does, you can use a USB adapter instead. If you don't want to spend much, avoid replacing the car stereo—it's not cost-effective and can be troublesome. Also, keep in mind: format your USB drive to FAT32 to avoid recognition issues, and don't fiddle with it too much while driving to stay focused. I often use this method and find it extremely convenient.

Want to play music from a USB in your buddy's old car? Just grab an FM transmitter! Plug it into the cigarette lighter, insert your USB, select a channel, and tune your car radio to match the frequency. Easy peasy! Or go cooler with a version—connect your phone to play tunes, and you can still plug in a USB. If there's an AUX port, just use an adapter and skip the hassle. Keep it simple.

To play music from a USB drive in an older car, try these tips: First, add an FM transmitter, which plugs into the cigarette lighter for convenience. Second, if your car has an old radio with an AUX input, connect a USB card reader for playback. If there's no AUX, consider using a cassette adapter with a USB device for auxiliary input, though the effect is limited. Upgrading to a new radio with USB functionality is the most reliable but costly. Comparatively, the FM method is the most practical, with low cost and quick installation. Upgrading the car stereo is suitable for long-term use. When choosing a USB drive, ensure it's compatible with FAT32 format, and remember to keep the volume at a safe level while driving.

I've experimented quite a bit with playing USB music in older cars. Initially tried FM transmitters: plug into cigarette lighter USB port, adjust frequency - convenient but poor signal especially in mountainous areas. Later upgraded to a new head unit with USB for better sound quality and stability. Also used AUX adapters with USB card readers for a simple low-cost solution. Key considerations when choosing: budget and safety - FM is cheapest for starters while new head units are long-term investments. Installation tips: ensure stable power supply, only store music files on USB to avoid malfunctions.
