How to listen to music from a car that lacks a USB port

Most of the car’s surround systems come with a USB port but some old versions lack this port. It can be frustrating if you have a dope music collection and you cannot enjoy it due to lack of a USB port. Investing in a new car stereo is costly but there are alternatives.

To add a USB port to your car stereo locate the FM transmitter. Most of the FM transmitters have the ability to read USB files. However, the sound quality is not that great. This is because the FM transmitter is congested with signals. If you want to improve the sound quality the other best option is to get an FM modulator.

Playing music from the USB port is a simple plug and play method. If you experience problems with playing your mp3 files then the problem could be how your head unit converts and reads the files.
