The Pioneer MVH-X580BT car radio wirelessly plays music from your smartphone or via Bluetooth. You can also listen to FM radio stations as well as tracks from a USB flash drive. The program MIXTRAX EZ seamlessly mixes separate tracks with nice transitions. The 3 inputs mean you can connect an amplifier or subwoofer for extra volume. Use the variable colors to adjust the display to your personal preferences. Choose a blue, green, or red background color for the screen and buttons. Connect your smartphone to the USB port to charge it.
