Because of the digital music revolution, there are some car stereos that come equipped with a universal serial bus (USB) port already. A USB port will allow you to plug in your flash drive and listen to all the music you have stored on there. A flash drive is a mobile storage device capable of holding thousands and thousands of songs. It can also store most other files, but music is the only one you will use with your car stereo. If your car stereo doesn't have a USB port built in, don't worry, you can buy a wireless FM transmitter that will allow your stereo to read songs from your USB flash drive.
Buy an FM transmitter for your car that supports USB flash drives. Most transmitters are compatible with MP3 players and SD cards as well.
Plug the transmitter into your car's cigarette lighter.
Plug your flash drive into the transmitter.
Set the transmitter to an FM station. Most transmitters allow you to choose from hundreds of FM stations. Once you choose a station, your music from you flash drive will be broadcast onto the station. You are now free to switch back and forth between the songs you have stored on your flash drive.
