Common Head Unit Sizes

There are two common types of head units on the market today that fit the majority of vehicle dashes: double-DIN and single-DIN head units. Double-DIN openings are the larger of the two. If your car has a double-DIN opening you can typically fit both single-DIN and double-DIN units in it. You'll just need to purchase the correct dash kit depending on the size you choose. Double-DIN openings are great for units like Multimedia/DVD, GPS, and other units that have a large display. If it's a single-DIN car stereo, you'll only be able to fit a single-DIN receiver. But don’t be alarmed, there’s tons of great head units out there that are designed for single-DIN dashes.

Here's a snapshot of the difference in sizing to help you determine which type you need. Both are for same vehicle, but have different sizes. In this case, you can have either a double or single DIN with the correct dash kit:

Another item to note is the age of your car, and how that impacts your likelihood of needing or wanting a new car stereo. If your car is newer than 10 years of age, your car might have multiple screens in different places on your dash. Here's an example of a 2009 Honda Accord:

These screens display different information from different systems in your car, and not just the audio. Replacing your head unit in cases like this could break functionality (like the top screen in a 2009 Honda Accord) if you install a new stereo if done incorrectly. Although it's definitely possible to upgrade in vehicles like this, you'll want to be sure that you have the correct wiring harnesses and it might be a little more expensive.

However, there are some vehicles that are still simple in newer vehicles. And if your car is older than 10 years of age it's likely it will have a more simple dash design and will be easier to upgrade. Take, for example, this 2005 Honda Civic Dash:

You'll notice that, in general it looks like there's a dedicated slot on the dash for the stereo. This means it's likely more simple to replace and it won't impact other systems and screens in the car. You'll still need a dash kit to make it a seamless fit, but this type of dash is a cheaper, better candidate for upgrading your car's stereo with a new and improved head unit.
