Listen to a powerful bass while driving, with the DSX-A212UI. This car radio has an Extra Bass button. This makes the lower tones of a song extra deep and dynamic. Which is handy when you prefer to listen to solid dance or rock music. Want to change the tone of the sound? Pick from 10 equalizer settings. This way, you create a sound reproduction that fits your taste best. Mute the sound of the vocals using the integrated karaoke function. This allows you to sing along to your favorite artists. Connect an iPhone or Android phone to the USB input. Use the radio buttons to browse through your music library.
