How to Replace a 2016 Ford Fusion Radio: Step-by-Step Guide

If you're looking to upgrade your audio experience in a 2016 Ford Fusion, replacing the factory radio is one of the most effective improvements you can make. A successful 2016 Ford Fusion radio replacement requires more than just buying a new head unit—it involves selecting compatible components like a double DIN or single DIN stereo, a proper dash kit (such as the Metra 99-5841B), and a wiring harness that matches your vehicle’s electrical system. This guide walks you through every step—from identifying your current setup to avoiding common installation mistakes—so you can complete the job confidently and correctly.

Understanding Your 2016 Ford Fusion's Factory Radio Setup

The 2016 Ford Fusion came with several factory-installed audio systems depending on trim level and optional packages. These include basic AM/FM radios with auxiliary inputs, SYNC 2 infotainment systems, and higher-end Sony or Bang & Olufsen premium audio setups 1. Before removing anything, it's crucial to identify which version your car has because this affects compatibility with aftermarket units.

Factory head units in the 2016 model typically use a non-standard size, meaning they don’t follow standard DIN dimensions. As such, when replacing them, you’ll need both a mounting solution and an adapter harness. The most common upgrade path is installing a double DIN (approximately 4 inches tall) touchscreen unit, but some users prefer single DIN models for a cleaner look or better integration with steering wheel controls.

Key considerations before starting:

• Does your Fusion have manual or automatic climate control? This impacts dash kit selection.
• Is SYNC integrated into the radio? If so, retaining functions like Bluetooth calling may require additional interfaces.
\li>Do you want Apple CarPlay or Android Auto? Most modern replacements support these features.

Choosing the Right Aftermarket Head Unit

When selecting a new stereo for your 2016 Ford Fusion, focus on functionality, fitment, and future-proofing. Popular choices include units from Pioneer, Kenwood, Sony, and Alpine, all offering various combinations of Bluetooth, navigation, USB connectivity, and smartphone integration.

Double DIN vs Single DIN: Double DIN units are larger and allow for built-in touchscreens, making them ideal for video playback and app-based navigation. However, fitting a double DIN unit into the Fusion’s dashboard usually requires modifying the lower bezel or using a specific kit like the Metra 99-5841B or 99-5854B. Single DIN units maintain the original profile but often lack large screens unless paired with a flip-out display.

Features to consider:

• Apple CarPlay & Android Auto: Essential for seamless smartphone mirroring.
• Bluetooth 5.0+: Ensures stable wireless audio streaming and hands-free calling.
• HD Radio Support: Provides clearer AM/FM reception where available.
• Steering Wheel Control Compatibility: Retains volume and track buttons on the steering wheel via a CAN bus interface.
• Backup Camera Input: Useful if adding or upgrading a rearview camera.

Dash Kits: Why You Need One and Which Fits Best

Because the 2016 Ford Fusion does not have a standard DIN-sized opening, a dash installation kit is required to mount an aftermarket radio securely and aesthetically. Without it, the unit will either not fit or leave unsightly gaps.

The two most commonly used kits are the Metra 99-5841B and the Metra 99-5854B, both designed specifically for 2013–2017 Fusions. While similar, there are subtle differences based on interior configuration:

Kit Model	Fits Years	Climate Control Type	Radio Size Supported	Special Features
Metra 99-5841B	2013–2017	Manual	Single or Double DIN	TurboTouch finish, factory-style texture
Metra 99-5854B	2015–2017	Automatic (touchscreen climate)	Single or Double DIN	TurboTactile buttons, integrates with touchscreen dash layout

📌 Important: Choosing the wrong dash kit can lead to misalignment or interference with HVAC controls. Always verify whether your Fusion has manual knobs or electronic climate settings before ordering. Vehicles equipped with SYNC 3 or advanced driver assistance systems (ADAS) often have the touchscreen climate panel, requiring the 99-5854B.

Wiring Harnesses and Electrical Integration

🔌 Replacing the radio isn’t just about physical fit—it also involves connecting power, ground, speakers, antenna, and data lines safely. The factory harness uses a proprietary connector, so you’ll need an adapter to link it to the aftermarket unit.

A typical setup includes:

• Metra 70-1721 Wiring Harness: Converts the OEM plug to standard ISO connections.
• Antenna Adapter: Connects the factory coaxial cable to the new radio’s F-type input.
• CAN Bus Interface (if needed): Required to retain steering wheel controls and sometimes instrument cluster messages.

⚡ Tip: Label each wire during disassembly and test the system before final reassembly. Use a multimeter to confirm power and ground connections. Never rely solely on color codes—verify with a wiring diagram specific to your Fusion’s VIN if possible.

Tools and Preparation Checklist

🛠️ Proper preparation prevents frustration and damage. Here’s what you’ll need:

• Trim removal tools (plastic pry bars)
• Phillips and Torx screwdrivers (T15/T20 common)
• Wire strippers/crimpers or terminal tool
• Electrical tape or heat shrink tubing
• Flashlight or work light
• Owner’s manual or service documentation
• New head unit, dash kit, and harnesses

⏱️ Estimated time: 1.5 to 3 hours for a DIYer with moderate experience. Working slowly reduces the risk of breaking clips or damaging airbag-related components.

Step-by-Step Installation Process
