Car Head Unit Upgrades: A Comprehensive Guide

Last Updated on 31 July 2023 by Lucas

If you’re looking to upgrade your car’s audio system, replacing the head unit is a great place to start. A new head unit can provide better sound quality, improved connectivity options, and additional features that can make driving more enjoyable. However, with so many different types of head units on the market, it can be overwhelming to choose the right one for your needs.

In this comprehensive guide to car head unit upgrades, you’ll learn about the different types of head units available and how to determine which one is right for you. You’ll also discover important features to look for in a head unit and tips for installing your new equipment. Whether you’re a seasoned car audio enthusiast or just starting out, this guide will provide all the information you need to make an informed decision about upgrading your car’s audio system.

Types of Car Head Units

If you’re looking for a car head unit upgrade, you should know that there are several types available to choose from, each with its own unique features and capabilities. After researching the Other H2s listed above, I suggest discussing two important factors when considering types of car head units: OEM vs. Aftermarket and Multimedia vs. Basic.

OEM (Original Equipment Manufacturer) head units are the ones that come pre-installed in your car by the manufacturer. These units may offer basic functionality such as radio and CD playback, but they often lack advanced features like Bluetooth connectivity or touchscreen displays. On the other hand, aftermarket head units are designed to replace your factory unit and offer more advanced features like navigation systems, smartphone integration, and better sound quality. When deciding between OEM or aftermarket head units for your car upgrade, consider what features you want versus what is already installed in your vehicle.

Multimedia head units provide a variety of entertainment options beyond just playing music CDs or tuning into radio stations. They often have built-in touchscreens that can display maps for GPS navigation or allow you to control media playback using Bluetooth connectivity with your phone. Basic head units typically only have simple displays for showing radio station frequencies or track information from CDs. Choosing between multimedia and basic head units can depend on how much time you spend in your car, whether you need access to navigation while driving frequently or if listening to music is enough for your daily commute needs. Ultimately, it’s important to weigh all these factors before making any decisions on which type of car head unit would be best suited for you!

Single-DIN vs. Double-DIN Head Units

When choosing between a single-DIN and double-DIN head unit, you’ll want to consider the size of your dashboard and your specific needs for features and functionality. Single-DIN head units are smaller and have a height of 2 inches, while double-DIN head units are twice the size with a height of 4 inches. If your car’s dashboard is spacious enough to accommodate the larger unit, then you may want to opt for a double-DIN head unit as it offers more screen real estate for displaying information.

On the other hand, if your dashboard can only fit a single-DIN head unit or if you’re looking for something that’s easier to install, then a single-DIN head unit may be the better choice. Single din vs. double din head unit compatibility is important because not all cars can accommodate both types of units. Additionally, installing a single DIN head unit is generally less complicated than installing its larger counterpart since it takes up less space in the dash. Ultimately, it depends on what works best for your car’s specific make and model as well as your personal preferences for features and functionality.

Touchscreens vs. Button-Based Head Units

Explore the benefits of upgrading to a touchscreen head unit over a button-based one, as it can significantly enhance your driving experience with its intuitive controls and modern features. Touchscreen head units offer a more user-friendly interface that allows you to easily navigate through different menus and options. With just a few taps, you can access various functions such as GPS navigation, music streaming, and hands-free calling. This feature eliminates the need for complicated buttons and knobs, making it easier and quicker for you to control your car’s audio system.

However, there are also some cons to consider when choosing between touchscreens and button-based head units. For one, touchscreen head units tend to be more expensive compared to their traditional counterparts. Additionally, they may require more attention from drivers in terms of keeping their eyes on the screen while making adjustments on the go. Despite these drawbacks, many drivers still prefer touchscreens due to their sleek look and overall user experience. Ultimately, it’s up to personal preference which type of head unit suits your needs best – whether it be a touchscreen or button-based one.

Features to Look for in a Car Head Unit

Don’t settle for a basic car audio system – take your driving experience to the next level by upgrading to a head unit with features that will make you want to stay on the road all day. When looking for the perfect head unit, one feature to consider is wireless options. With Bluetooth connectivity, you can easily stream music from your phone or other devices without having to fuss with cords and cables. Plus, if you’re someone who relies heavily on GPS navigation apps like Google Maps or Waze, a head unit with wireless Android Auto or Apple CarPlay capabilities can be a game-changer.

Another important feature to look for in a car head unit is display resolution. A higher resolution screen can provide clearer visuals and make it easier to read text and view images while driving. This is especially crucial when using GPS navigation or watching videos in your car during long trips. Additionally, some head units come equipped with touchscreens that have adjustable brightness levels and anti-glare properties, making them easier to use even on sunny days. By choosing a head unit with these advanced features, you’ll be able to enjoy all of your favorite media while staying safe and comfortable behind the wheel.

Connectivity Options: Bluetooth, USB, and Auxiliary

Having multiple connectivity options, such as Bluetooth, USB, and auxiliary, is essential for a seamless audio experience in your vehicle. With Bluetooth technology, you can easily pair your smartphone or other compatible devices to the head unit without having to deal with pesky wires. This allows for convenient audio streaming directly from your device to the car’s speakers.

USB connectivity is another great option that allows you to play music directly from a flash drive or other USB-compatible device. Some head units even come equipped with multiple USB ports, making it easy to switch between different devices. Auxiliary input is also a popular choice for those who want to connect their phone or other audio devices directly with a cable. It’s important to ensure compatibility with different smartphone models when choosing a head unit so that you can take full advantage of all these connectivity options.

Navigation Systems and GPS

You’ll love the convenience of having a built-in navigation system and GPS in your vehicle. Not only will it save you time and hassle, but it can also improve your safety on the road. With voice commands, you can easily input your destination without taking your hands off the wheel or eyes off the road.

A good navigation system should also provide real-time traffic updates to help you avoid congestion and accidents along your route. This feature alone can save you from hours of sitting in bumper-to-bumper traffic. So if you’re someone who frequently travels to new places or simply wants a more efficient commute, investing in a quality navigation system with GPS is definitely worth considering as part of your car head unit upgrade.

Apple CarPlay and Android Auto Compatibility

If you want to experience a more seamless and connected driving experience, it’s time to consider integrating your smartphone with your car through Apple CarPlay or Android Auto. These systems allow you to access your phone’s apps, maps, and music directly from the car’s dashboard display. You can make calls, send texts, and even use voice control to operate certain features without taking your hands off the steering wheel.

One of the key differences between Apple CarPlay and Android Auto is their connection type. While both systems offer wired connections for optimal performance, they also have wireless capabilities depending on your car’s compatibility. Additionally, both systems prioritise safety by minimising distractions while driving through intuitive voice control capabilities. With these features at hand, you can stay focused on the road while still enjoying all the benefits of having your phone integrated with your car’s head unit.

Sound Quality and Audio Settings

Get ready to experience amazing sound quality in your car with easy-to-use audio settings that will make your favorite songs come alive. One of the most important factors that contribute to good sound quality is speaker placement. Make sure that your speakers are positioned correctly for optimal listening. This means placing them at ear level and angling them towards you for a more immersive listening experience.

Another crucial aspect of sound quality is equalizer settings. Your car head unit likely has a built-in equalizer, which allows you to adjust the levels of different frequencies in your music. Experiment with these settings until you find what works best for you and your car’s acoustics. With just a few tweaks, you can bring out the bass, treble, or midrange in your music like never before. Don’t be afraid to play around with the settings until you achieve the perfect balance that suits your taste.

Installing Your New Car Head Unit

Now that you’ve learned how to fine-tune your car head unit’s audio settings to produce the best sound quality possible, it’s time to move on to the exciting part: installing your new head unit! But before we dive into the wiring process, it’s important to note that not all cars are compatible with aftermarket head units. Some factory systems have integrated climate controls or other features that can’t be easily replaced. Be sure to do your research and check if your vehicle is compatible before making any purchases.

Assuming your car is compatible, the first step in installing a new head unit is disconnecting the old one. This involves removing trim panels, unscrewing screws or bolts holding the old unit in place, and unplugging any wiring harnesses and antenna cables connected to it. Once you’ve done this, you’ll need to connect a wiring harness adapter (sold separately) between the factory wiring and the wires on your new head unit. These adapters make installation much easier by providing colour-coded wires that match up with those on both ends of the connection. After connecting everything properly, test out the system by turning it on and checking for any issues like blown fuses or misconnected wires. With some patience and a little bit of know-how, replacing an old car head unit with a new one can be a fun DIY project that results in improved sound quality and updated features for your ride!

Troubleshooting Common Issues with Car Head Unit Upgrades

When upgrading your car’s audio system, it’s important to know how to troubleshoot common issues that may arise in order to ensure optimal performance and enjoyment of your new setup. One issue you may encounter is wiring problems. If you notice that certain speakers aren’t working or the sound quality isn’t as good as expected, it may be due to faulty wiring. The first step in diagnosing wiring issues is to check all connections and make sure they’re secure. You should also inspect the wires for any signs of damage or wear and tear.

Another issue you might face when upgrading your car head unit is Bluetooth connectivity problems. If your device doesn’t connect or stay connected, it can be frustrating and impact your listening experience. To troubleshoot this problem, start by making sure Bluetooth is turned on and within range of the head unit. Also, verify that both devices are compatible with each other and have the latest software updates installed. It’s also a good idea to clear out any previously paired devices from the head unit’s memory before attempting another connection.


So, there you have it! You are now equipped with a comprehensive guide to car head unit upgrades. Whether you’re looking for better sound quality, more connectivity options, or just a new look for your car’s dashboard, upgrading your head unit can make a big difference.

Remember to consider the type of head unit you want (single-DIN vs. double-DIN), whether or not you want a touchscreen interface, and what features are important to you (like Bluetooth connectivity and Apple CarPlay compatibility). With these factors in mind, you’ll be able to choose the best head unit for your needs and install it easily using our step-by-step instructions. Happy upgrading!
