If you are not technically minded, you can simply measure the cavity in your vehicle and if it matches those dimensions, you have a single DIN and you need a single DIN universal car stereo. However, some vehicles have a double-DIN.

Which is better – single-DIN or double-DIN? Well, it depends. For basic stereo functions like power and sound controls, they're pretty much the same. Double-DIN stereos have more room for the controls, so they tend to be easier to use.

Two different DIN measurements are used to describe car stereos and infotainment systems. The first is Single-DIN, which refers to a rectangular opening in the dashboard that measures 2 inches high by 7 inches wide. Double-DIN — or 2-DIN — doubles the height to 4 inches while keeping the same width.
