What Is the Definition of a Single DIN Car Stereo?

DIN is an automobile audio standard developed by the German standards organization Deutsches Institut für Normung (DIN). It regulates the height and breadth of automobile head units. When a unit is referred to be a single DIN vehicle stereo or a single DIN car radio, it signifies that it meets the DIN height and width requirements.

What exactly is the DIN Standard?

This standard is used by automakers and automobile radio manufacturers all around the world, which is why most head units are interchangeable. While the wiring is not standardized, it is because of the DIN standard that OEM car stereos may be replaced with aftermarket devices.Despite the fact that the DIN standard only requires a single height and breadth, head unit manufacturers create devices that are twice as tall. These double-tall units are known as double DIN because they are twice as tall as the single DIN standard. A few head units are 1.5 times the height of the DIN standard, making them technically 1.5 DIN.

How to Determine Whether Your Car Radio Is Single DIN

The simplest way to determine whether a vehicle radio is single DIN is to measure it. If the radio is less than two inches tall, it is most likely a single DIN. It's double DIN if it's around four inches tall. A 1.5 DIN radio, which is fairly uncommon, lies between those dimensions. There are no additional DIN measures that are standardized.Some cars are more difficult to maneuver than others. For example, if a dash has three vertically stacked slots that are all approximately two inches high and only one of them is occupied by an OEM radio, it's most likely a standard single DIN head unit. It is difficult to predict if a bigger head unit can be accommodated in such instances.Consoles with gaps above or below a single DIN head unit were often intended to hold a CD player or other piece of audio equipment. Certain auto dealers and audio experts may have original factory equipment lying around in such a circumstance.

How to Replace a Single DIN Car Radio

When it comes time to replace your single DIN vehicle radio, the most convenient alternative is to purchase a single DIN aftermarket device. While there may be minor variations in fit and finish, most single DIN aftermarket units are intended to be fitted in an adjustable collar that allows for insertion in practically any single DIN slot.

Changing a Single DIN Radio to a Double DIN Radio

Because double DIN head units are twice as tall as single DIN head units, you can always convert from double to single, but the opposite may be difficult.Before making such an update, it is critical to first measure the slots and ensure that they are accessible. The extra slot should be two inches high. Some automobiles contain fake slots that appear to be meant to receive a device such as a CD player but are actually intended for storage. Such an aperture may or may not accommodate a 1.5 DIN unit.You may also discover that there is no detachable cover, and even if the housing is removed, there may be a tangle of cables or ducting that prevents the installation of a double DIN head unit.

Dash Space and Other Challenges

Assuming your console has enough capacity, the next issue you'll face is wiring. Even if you replace a single DIN head unit with a double DIN head unit, the wire harness connectors aren't always the same. To splice a new connector into the existing wire harness, you'll need to obtain an adapter or utilize a wiring schematic.The second difficulty is that even if the console has a blank slot beneath the head unit, it may be molded into the dash. Even if it is detachable, it is unlikely to accommodate more than a single DIN device, such as a CD player.If you wish to replace a single DIN head unit with a double DIN device, you may need to remove the dash section that divides the two slots.If your vehicle offers a double DIN head unit option, you may be possible to replace the present dash or center console bezel with one intended for a double DIN head unit.

Why is Double DIN used?

Before you go to the trouble of replacing your single DIN radio with a double DIN head unit, consider whether it's worth it. Although double DIN head units provide greater real estate for features like as touchscreens and internal room for amenities such as strong amplifiers and built-in CD changers, the costs soon pile up.Single DIN head units with slide-out screens are available if you need a large touchscreen. You may also install components such as an external amplifier or CD changer without having to cut into the dash bezel, and you might be able to use that extra single DIN slot for a graphic equalizer or another helpful audio component.
