Most of the customers who come to our store for a new car radio want a car radio with USB, to which they can connect a USB flash drive full of their favorite music. A modern car radio with USB input can also charge your mobile phone. The USB car radio can have an input both on the front panel and from the back of the car radio, output on a cable. Bluetooth car radios with USB are very popular, where you can choose whether to play music via Bluetooth or from a USB stick.
