In-car technology has advanced significantly over the past few years, and upgrading your vehicle’s factory radio to an aftermarket head unit can bring your car up to speed with modern features like Apple CarPlay, Android Auto, and Bluetooth connectivity.
However, when installing a new head unit, one of the most critical factors to consider is retaining the use of your steering wheel controls. These controls allow for safe and convenient management of your audio system, keeping your focus on the road.
In this article, we’ll guide you through the benefits of upgrading your car’s head unit, explain why maintaining steering wheel control functionality is essential, and detail the components needed for a smooth and efficient installation.
Why Upgrade Your Car’s Radio?
Factory-installed radios in older vehicles often lack the advanced features we now expect from modern infotainment systems. Here are a few reasons why upgrading to an aftermarket head unit makes sense:
- Apple CarPlay & Android Auto Integration: With these systems, you can connect your smartphone to your car’s display, enabling access to apps, navigation, music streaming, and hands-free calling. They provide a safer, more convenient way to use your phone while driving.
- Bluetooth Connectivity: Bluetooth allows you to make hands-free calls and wirelessly stream music from your phone, making every trip more enjoyable.
- Enhanced Audio Quality: Aftermarket radios typically offer better sound performance, thanks to built-in equalizers and support for external audio components like subwoofers and amplifiers.
An upgraded head unit can modernize your vehicle’s technology, making daily drives more enjoyable and safer. However, to fully realize these benefits, it’s important not to lose the use of your steering wheel controls.
Maintaining Steering Wheel Control Functionality
Steering wheel controls are more than just a luxury—they are a vital safety feature that allows you to operate your vehicle’s audio system without taking your hands off the wheel. When upgrading to an aftermarket radio, a steering wheel control adapter is needed to ensure these controls continue to work with the new head unit.
Key Benefits of Retaining Steering Wheel Controls:
- Safety: Steering wheel controls enable you to adjust the volume, skip tracks, or answer calls without diverting your attention from the road.
- Convenience: With steering wheel controls, managing your in-car entertainment becomes more seamless and intuitive.
- Preserving Original Features: By retaining steering wheel controls, you maintain the functionality that came with your vehicle, even after upgrading to a new, more advanced head unit.

Essential Components for an Aftermarket Head Unit Installation
A successful radio upgrade requires more than just purchasing a new head unit. You’ll need specific components to ensure a professional and functional installation:
1. Fascia Plate
Each vehicle has a unique dashboard design, and the fascia plate ensures that your new radio fits perfectly into the space left by the old factory unit. Whether you’re installing a Double DIN or Single DIN head unit, a vehicle-specific fascia plate is required for a neat and flush installation.
2. Harness Adapter
Your vehicle’s wiring system is designed for the factory radio, and aftermarket head units often have different connectors. A harness adapter bridges this gap, allowing you to connect the new radio to your car’s electrical system without cutting or modifying the original wiring.
- CAN Bus Compatibility: If your vehicle has a CAN Bus system, you’ll need a CAN Bus adapter to retain full functionality of the vehicle’s data systems, such as steering wheel controls and ignition power.

3. Antenna Adapter
To ensure proper radio reception after installing your new head unit, you’ll need an antenna adapter. This adapter connects the vehicle’s factory antenna to the new radio, allowing you to enjoy uninterrupted FM/AM radio.

Step-by-Step Guide to Installing a New Head Unit
Once you have gathered the necessary parts, follow these steps to install your new head unit and retain your steering wheel controls.
Step 1: Disconnect the Battery
To prevent electrical issues during installation, disconnect the vehicle’s battery before starting the process.
Step 2: Remove the Factory Radio
Use a trim removal tool to gently pry away the dashboard trim surrounding the radio. Unscrew the mounting screws holding the radio in place, then pull it out and disconnect the wiring and antenna cables.
Step 3: Install the Fascia Plate
Once the factory radio is removed, install the appropriate fascia plate for your new head unit. This step ensures that the new unit fits seamlessly into the dashboard.
Step 4: Connect the Harness Adapter
Plug the harness adapter into your vehicle’s factory wiring harness. This ensures that the new head unit will receive power and audio signals from the car’s system.
Step 5: Install the Steering Wheel Control Adapter
Connect the steering wheel control adapter to both the new head unit and the vehicle’s original wiring. This will allow the new system to communicate with the steering wheel controls, ensuring their functionality is retained.
Step 6: Attach the Antenna Adapter
Connect the antenna adapter to the car’s antenna plug and the new radio. This ensures continued FM/AM radio reception.
Step 7: Install the New Head Unit
Slide the new head unit into place, secure it with the provided screws, and reconnect the wiring. Once everything is connected, power the system on to ensure all functions are working correctly.
Step 8: Reassemble the Dashboard
Once the head unit is installed and tested, reattach the dashboard trim to complete the installation. Make sure everything fits snugly for a professional finish.
