How to download songs in the car. If you want to download songs in the car, you must be able to download music software on the central control display in the car. If you can't download music software, you can't download songs in the car. If you can download music software, open the mobile hotspot, connect directly to the mobile hotspot, open the software and download it. Cars can play music in the following ways: 1. CD. Go to the video store, buy a few CDs, plug them into the car's central control and play them. If you can't buy one, you can use your own burning software on your computer to burn the songs onto a blank white burning disc, and then take it to the car to play. 2. If equipped with car Bluetooth, connect your phone to the car Bluetooth and play. If you don’t have car Bluetooth, you can buy one, plug it into the car Bluetooth through the cigarette lighter, and then connect it to your mobile phone for playback. 3. If there is an AUX interface built into the car, you can play it directly by connecting it to your mobile phone. 4. If the car has a USB interface, you can play it by connecting a USB flash drive. Buy yourself a USB flash drive, connect it to your computer, download the songs to the USB flash drive, and then plug the USB flash drive into the car's USB port to play. It should be noted that ordinary models can support MP3 format, but many other models do not, so when downloading, be sure to download music in MP3 format.
