Automotive head units, often called car receivers or infotainment systems, have evolved far beyond the past’s basic AM/FM radios.
In this article, we’ll look into the multifaceted world of vehicle audio, exploring the myriad features and functionalities of modern head units.
From traditional radio and CDs to cutting-edge technologies like Android Auto and gesture recognition, these devices have become essential for a transformative in-car experience.
Join us as we demystify the realm of automotive head units and help you navigate the options available from popular aftermarket brands like Kenwood, Pioneer, Sony, and Alpine.
Car Receiver Types
Car receivers come in various sizes and formats, with single-DIN and double-DIN units being the most common. Let’s look into the differences between these two types and their distinctive features.
1. Single-DIN Units:
- Size: Single-DIN receivers typically measure about 2 inches (50mm) in height and 7 inches (180mm) in width. They are the standard size for most car stereos.
- Features: While they may have a smaller form factor, single-DIN units still offer a wide range of features. These include AM/FM radio, CD players, USB ports for music playback, Bluetooth connectivity for hands-free calling, and often support for smartphone integration like Android Auto and Apple CarPlay.
- Benefits: Single-DIN units are a good choice for vehicles with limited dashboard space. They are also relatively easy to install and are compatible with a wide range of car models.
2. Double-DIN Units:
- Size: Double-DIN receivers are twice the height of single-DIN units, measuring approximately 4 inches (100mm) in height and 7 inches (180mm) in width. This larger size allows for more screen real estate.
- Features: Double-DIN units excel in offering larger touchscreen displays, which are ideal for GPS navigation, multimedia, and viewing vehicle information. They often have advanced entertainment features, including higher-quality audio components, larger touchscreen interfaces, and more connectivity options.
- Benefits: These units provide a more immersive and user-friendly experience, especially for tasks like navigating and operating multimedia features. They are popular for those who prioritise a rich in-car entertainment experience.
Audio Sources on Head Units
Modern head units in cars offer various audio sources beyond music to enhance the in-car entertainment experience. These sources cater to diverse preferences and technological advancements. Here are some of the audio sources you can find in modern head units:
- AM/FM Radio: Traditional AM and FM radio reception remains a standard feature in most head units, allowing drivers to tune in to local stations for news, talk shows, and more.
- Satellite Radio: Many head units are equipped with satellite radio receivers, offering access to various channels with music, talk shows, sports, and other content, often with no commercials.
- CDs and Cassettes: While less common than before, some vehicles still include CD players and even cassette decks, allowing drivers to enjoy their physical music collections.
- USB Ports: Most modern head units come with USB ports, enabling you to connect USB drives loaded with your favourite songs. This is a convenient way to bring your music library on the road.
- Bluetooth Connectivity: Bluetooth technology allows drivers to pair their smartphones or other devices with the head unit. This enables wireless audio streaming, hands-free calling, and access to voice assistants.
- Auxiliary Input: An auxiliary (AUX) input is often available for connecting external devices like MP3 players, smartphones, or portable music players through a 3.5mm audio cable.
- Streaming Services: Many head units now support popular streaming services like Spotify, Apple Music, and Pandora. Drivers can access these services via a smartphone connection or integrated apps.
- Navigation Guidance: Some head units provide guidance with voice prompts, enhancing the in-car experience by offering directions and real-time traffic updates.

- DVD and Video Playback: In some vehicles, head units have screens for playing DVDs or digital video files. Passengers can enjoy movies and videos during long journeys.
- HD Radio: High-definition (HD) radio provides improved audio quality and additional sub-channels within AM and FM frequencies, offering more content options.
- CarPlay and Android Auto: These smartphone integration platforms allow you to mirror your phone’s interface on the head unit’s screen, providing access to apps, navigation, and messaging.
Modern head units are designed to provide a diverse range of audio sources to cater to the preferences of drivers and passengers, making the in-car entertainment experience more enjoyable and customisable. Whether you prefer traditional radio, your own music collection, or the latest streaming services, there’s likely an option to suit your needs.
Bluetooth, Wi-Fi, and smartphone integration, particularly through Android Auto and Apple CarPlay, have revolutionised the in-car experience by offering seamless connectivity and enhancing safety.
Bluetooth connectivity allows drivers to wirelessly pair their smartphones with the car’s head unit. This enables hands-free calling, music streaming, and access to voice assistants, reducing distractions and improving safety on the road. It’s a vital feature for maintaining connectivity while keeping focus on driving.
Wi-Fi connectivity is increasingly important, enabling real-time updates for maps, traffic information, and software upgrades. Passengers can also stay connected to the internet, making long journeys more enjoyable and productive.
Additionally, Wi-Fi can facilitate over-the-air updates, keeping the car’s software up-to-date with the latest features and security patches.
Android Auto and Apple CarPlay take smartphone integration to the next level by mirroring the phone’s interface on the car’s touchscreen. This means seamless access to navigation, music apps, messaging, and more, all while keeping the driver’s eyes on the road and hands on the wheel.
These systems make it easy to integrate the capabilities of smartphones into the car’s infotainment system, ensuring a safe and connected driving experience.
Audio enhancements integrated into modern head units are pivotal in elevating the in-car audio experience. These enhancements not only improve sound quality but also offer a range of features that cater to diverse audio preferences:

- Equalisation and Sound Customization: Advanced equaliser settings allow users to fine-tune the audio to their liking, adjusting bass, treble, and other parameters to create a personalised sound profile.
- Time Alignment: Time alignment technology helps align the audio from each speaker to ensure that sound reaches the listener’s ears simultaneously, resulting in a more natural and immersive listening experience.
- Digital Signal Processing (DSP): DSP technology enables precise audio processing, correcting sound imperfections and creating a more balanced and enjoyable soundstage.
- Crossfade and Mixing: Some head units offer crossfade and mixing features, enabling seamless transitions between tracks and the ability to create customised playlists or DJ-like effects.

- Multi-Zone Audio: In vehicles with multiple audio zones, head units can control and customise audio output for different areas within the car, providing a tailored listening experience for passengers.
- Integration with Smartphone Apps: Integration with apps like Spotify, Apple Music, and podcasts enhances the head unit’s capabilities, allowing users to access their favourite content seamlessly.
- Wireless Audio Streaming: Bluetooth connectivity allows wireless audio streaming from smartphones and other devices, making playing music without physical connections easy.
