Car Stereo Installation & Accessories for your 2017 Prius C

Installing an aftermarket head unit involves more than just choosing a screen; it's about building a bridge between new technology and your vehicle's factory architecture. Without the right installation accessories, a high-end receiver can't provide the seamless look or the integrated functionality your car was designed with. From dash kits that match your interior texture to complex digital interfaces that talk to your vehicle's computer, these components are what make a professional-grade installation possible.

Whether you're looking to retain your steering wheel controls, adapt a proprietary antenna plug, or ensure your new Double-DIN screen sits flush in the dash, we carry a comprehensive selection of gear from industry leaders like Metra, Scosche, PAC, and iDatalink.

Use our FitFinder to find the exact parts required for your specific year, make, and model. It's the most reliable way to ensure your DIY project results in a factory-finished look.

It's a no-brainer. Get your installation gear here.

    FAQ Frequently asked questions in Car Stereo Installation & Accessories


    In most modern vehicles, the factory radio is part of a larger, integrated dash panel rather than a standardized rectangular box. A vehicle-specific dash kit provides the necessary brackets and trim pieces to adapt the universal ISO-mount of an aftermarket stereo to the unique shape and mounting points of your dashboard.

    Choosing the right Car Stereo Installation & Accessories begins with understanding your vehicle's make, model, and year. This information helps you select compatible wiring harnesses and mounting kits. Next, consider your audio preferences. If you're looking to upgrade your car's sound system significantly, opt for an amplifier installation kit that matches your amplifier's power requirements.Additionally, check the head unit's compatibility with your smartphone and other devices.

    Features like Bluetooth connectivity, Apple CarPlay, or Android Auto can greatly enhance your driving experience. Ensure that the accessories you choose align with your car audio goals, whether it's improved sound quality, convenience, or connectivity.

    Not if you use a Steering Wheel Control (SWC) interface. These modules translate the signals from your factory buttons into a language your new stereo understands. Many modern integration harnesses, like the iDatalink Maestro, include this functionality along with the ability to display engine data and tire pressure on your new screen.
    We strongly recommend using a wiring harness. Cutting factory wires is permanent, increases the risk of short circuits, and can void your vehicle's electrical warranty. A harness allows you to do all your soldering or crimping on the bench, then simply plug the new assembly into the factory connector without damaging the car's original wiring.

    Safety is paramount during Car Stereo Installation & Accessories installation. Start by disconnecting the car's battery to avoid electrical accidents. When handling wiring and electrical connections, follow proper insulation techniques to prevent short circuits or fires. Secure all cables and wires away from moving parts like steering columns and pedals.

    During the installation of amplifiers and subwoofers, ensure that they are securely mounted to prevent movement while driving. Avoid drilling into gas tanks, brake lines, or other sensitive areas when installing components. It's also a good practice to have a fire extinguisher and a first aid kit on hand in case of emergencies.

    All About

    Car Stereo Installation & Accessories

    Navigating the hardware required for a radio swap can be confusing. To get the job done right the first time, it's helpful to understand the specific role each accessory plays in the signal chain and the physical assembly.

    Dash Kits: The Cosmetic Foundation

    The dash kit is what ensures your new stereo doesn't look like an afterthought. These kits are engineered to match the exact color, texture, and contour of your factory dash.

    • Single-DIN Kits: Feature a 2-inch tall opening, often including a storage pocket to fill the extra space.
    • Double-DIN Kits: Feature a 4-inch tall opening designed for large touchscreens and multimedia receivers.
    • Multi-Kits: Versatile designs that can be configured for either size depending on your hardware choice.

    Wiring Harnesses and Data Interfaces

    The wiring harness is the electrical nervous system of your install.

    • Standard Harnesses: Provide basic power, ground, and speaker connections for older vehicles.
    • Data Interfaces: Required for modern vehicles with CAN-bus systems. These modules "talk" to the car’s computer to provide a 12V switched power source (which many new cars lack at the radio) and retain safety features like door chimes, OnStar, or factory amplifiers.

    Steering Wheel and Camera Retention

    Convenience and safety shouldn't be sacrificed for better sound. Dedicated interfaces allow you to keep your hands on the wheel and your eyes on the screen when reversing. If your vehicle has a factory backup camera, a camera retention adapter allows you to feed that video signal directly into your new touchscreen's RCA input.

    Professional Installation Tools

    Using the wrong tools can lead to cracked plastic or scratched leather. A set of nylon trim removal tools is essential for prying off dash panels without leaving permanent pry marks. Additionally, we recommend high-quality crimp connectors or heat-shrink tubing to ensure your electrical connections remain stable through years of vehicle vibration.
