What Is a Double DIN Car Radio? – Double DIN Explained

If your car comes with a double-DIN head unit, chances are it lacks features and the touchscreen (if it has one at all) is weak and nearly non-responsive. This requires an upgrade. While a current single-din stereo may compete with your prior double-DIN head unit, we recommend upgrading to a double din head unit for a technology-packed and stylish improvement to your car’s music system.

Although most recent aftermarket double-DIN systems are slightly more expensive, the features they offer are assured to provide good value for money. Aside from the obvious auditory and visual enhancements, they can also be utilized for navigation, communication, entertainment, and other purposes.

Now, let’s find out with me about “what is a double din car radio?”! In short, double din means that vehicle radios of this size are effectively two single-DIN head units stacked on top of one another. Continue reading for a comprehensive overview!

What Defines 2 DIN Car Stereo?



DIN is an abbreviation for Deutsches Institut für Normung. This German standards body that developed the initial standard for automotive head units that we still use today. The DIN 75490 standard specifies that a head unit shall be 180 mm long and 50 mm height when seen from the front.

DIN 75490 was accepted as ISO 7736 by the International Standards Organization, and it is utilized by automakers all over the globe. However, because the Deutsches Institut für Normung developed the original standard, head units that meet this form factor are still called “DIN car radios.”

Despite ISO 7736/DIN 75490 being the global standard for automotive radios, there are significant differences and potential fit concerns. The most common variation of DIN 75490 is known as “double DIN,” so double din mean on a car stereo is effectively two single DIN head units placed on top of one another. To that purpose, the double din radio dimensions are 150 mm long, but 100 mm in height rather than 50 mm.

Of all, depth is significant as well, but neither ISO 7736 nor DIN 75490 stipulate it. None of these standards even specifies a depth range for automotive head units to follow. As a result, certain head units may not fit some vehicles with very shallow head unit receptacles.

Most current head units are adequately sized for most modern automobiles, although there are a few outliers. Thus, it’s still important to check a fit guideline before buying a product. While merely determining if a head unit is a single or double din or any less popular format factor is typically sufficient, reviewing a fit guideline eliminates any uncertainty.

Why Was Double DIN Implemented?



Because a variety of new automobiles of varied types are made all over the globe, the Germans created 178mm x 100mm measures as a common standard to make the process more efficient. There were single-DIN devices as well as double-DIN vehicle stereos, which were practically double the size. This was done to allow for additional power, performance, and features like digital screens as technology improved. Even though this standardization provided an exact width and height measurement, depth was never obtained.

What Characteristics Does a Double DIN Stereo Have?

Nowadays, the most recent 2 din car stereo on the marketplace meets all expectations. Most now have a huge digital display that is frequently HD ready and touchscreen. This is done to highlight current features like built-in DVD players, navigation, screen mirroring, and gameplay.

Radio (Single DIN or Double DIN)

To determine whether you require a “2 DIN vehicle radio,” measure the faceplate of your current head unit. If it’s around 7 inches long by 2 inches in height, it’s a single DIN head unit that must be replaced with the other single DIN unit.

If your radio is approximately 7 inches in length by 4 inches in height, it is double DIN. In that situation, you may either install a second double din radio or utilize a single din device with an installation kit. There is also a 1.5 DIN size in the middle, although it is rarely utilized. These headpieces are around 3 inches tall, as the name suggests.

Q&A About a Double DIN Car Radio

Is 2 DIN preferable to 1 DIN?

You may relax if you’re worried about replacing a 2-DIN head unit with a 1-DIN vehicle radio for manufacturing issues. Double-DIN head units are not always superior to single-DIN head units. Despite having a greater internal capacity for components (such as built-in amplifiers), the finest head units include preamp outputs, allowing a specialized vehicle amplifier to handle the heavy lifting.

The major advantage of double-DIN head units is often in the display, as double-DIN has significantly greater screen real estate than single-DIN. Most of the top touchscreen head units are double-DIN, which also implies that most of the greatest video head units are in this category. However, there are a lot of fantastic single-DIN head units with flip-out touchscreens, so selecting one form factor over the other is purely a matter of opinion.

What may be used in the replacement of two DIN car stereos?

Single-DIN head units can only be changed with other single-DIN units. However, if your car comes with a double-DIN radio, you have more possibilities. You might even be able to place an extra component in the bracket, such as a visual equalizer. Some head unit brackets and installation kits contain a built-in pocket for CDs, your smartphone or Media player, or other small items.
