Buying Guide for the Best Head Units
Choosing the right head unit for your car is an important decision, as it serves as the central control for your audio, media, and sometimes even vehicle functions. A good head unit can greatly enhance your driving experience by offering better sound quality, modern connectivity features, and easier control of your entertainment. Before making a choice, think about how you use your car stereo on a day-to-day basis, what devices you want to connect, and what type of user experience you value most.Screen Size and TypeScreen size determines how large and easy-to-read the display is, while screen type refers to whether it’s a standard LCD, capacitive touchscreen, or even a simple display with buttons. Bigger and touch-friendly screens make navigation and control much easier, especially for those who use maps or handle playlists while driving. Compact displays with basic buttons suit those who value simplicity and just want to enjoy radio or music without too many bells and whistles. Consider how much you interact with your stereo and if you frequently use features like navigation or video playback—a larger, high-quality touchscreen would be ideal. For those who mostly use radio or simple functions, a smaller or non-touch display works just fine.
Connectivity (Bluetooth, USB, AUX, Wi-Fi)Connectivity options let you link your head unit to smartphones, music players, external storage, or even wireless networks. Bluetooth is important for hands-free calling and wireless music streaming, while USB and AUX provide direct connections for better sound quality or charging devices. Wi-Fi connectivity unlocks features like wireless Apple CarPlay or Android Auto. If you often stream music, take calls, or want seamless phone integration, look for models with robust Bluetooth and perhaps Wi-Fi options. If you have older music sources or just need simple playback, AUX and USB might be all you require.
Audio Output/Power (Wattage, Preamp Outputs)Audio output and power refers to how much amplification the head unit provides and how many connection points there are for external amplifiers or speakers. Higher wattage means louder and potentially clearer sound, especially if you're powering speakers directly from the head unit. Preamp outputs are necessary if you plan to add aftermarket amplifiers or a subwoofer for a richer sound system. If you’re an audiophile or planning a custom sound setup, look for head units with higher power output and multiple preamp outputs. For casual listeners using factory speakers, standard output ratings will be sufficient.
Smartphone Integration (Apple CarPlay, Android Auto, MirrorLink)Smartphone integration allows your head unit to mirror your phone’s interface, making it easier and safer to use navigation, send messages, and play music. Apple CarPlay and Android Auto are the most popular systems, providing a familiar interface with voice control features. This is especially important for those who rely on smartphone navigation or like to use voice commands. If you want to use your phone’s apps safely while driving, prioritize head units with these integrations. If you rarely use your smartphone in the car, this feature might not be as important.
Installation Size (Single DIN, Double DIN)DIN size refers to the physical dimensions of the head unit and determines whether it fits in your car’s dashboard. Single DIN units are smaller and fit most cars but have limited screen space and often fewer features. Double DIN units are twice as tall, allowing for larger screens and more advanced features, but only fit in dashboards designed for this size. Make sure to check your car’s compatibility before buying. Choose double DIN for bigger, feature-rich units if your car supports it, or single DIN for compact, straightforward installations.
Expandability and Features (Navigation, Rear Camera Input, Steering Wheel Controls)Expandability refers to the head unit’s ability to work with additional features like built-in GPS navigation, rear-view camera input, and compatibility with steering wheel controls. Navigation is helpful if you frequently drive to new places without using your phone. Rear camera support adds safety when reversing, and steering wheel integration keeps you safer by allowing hands-on-the-wheel control. Decide what extra features you’d actually use—drivers valuing safety or often on the road benefit the most from these expandability options.
