A car radio has to fit any car, so there are two standard dimensions for car radios: 1-DIN and 2-DIN radios. On this page, you can find all 1-DIN and 2-DIN car radios. The 1-DIN radios are the traditional car radios with a narrow display. The dimensions of 1-DIN car radios are 180mm x 50mm with a depth of 150mm.
