Upgrading the 2017 Toyota 86 head unit is one of the most impactful modifications you can make to modernize the driving experience in your boxer-engine sports car. While the factory stereo provides decent sound quality, it lacks the connectivity, navigation, and power necessary to integrate a smartphone seamlessly into your daily drive. This guide explores the reasons for the upgrade, the critical technical considerations, and the best choices available for transforming the cabin of your FA20 or FA24 powered 86.
Why Upgrade Your 2017 86’s Infotainment System
The primary motivation for a 2017 Toyota 86 head unit upgrade is the integration of modern smartphone connectivity. Apple CarPlay and Android Auto were not standard or even available options when this model was released, leaving drivers to rely solely on Bluetooth for calls and basic audio streaming. An aftermarket head unit solves this by providing a high-resolution touchscreen interface that allows direct access to apps, maps, and music stored on your phone. Furthermore, the factory radio often feels outdated in terms of processing speed and graphical interface, whereas modern digital screens offer a much more intuitive and responsive user experience.
Understanding The Factory Wiring Harness
Before purchasing any unit, understanding the specific wiring configuration of your 2017 86 is essential to ensure a plug-and-play installation. Toyota utilizes a specific plug designation for this model year, which carries audio, power, and steering control signals to the head unit. When selecting a new deck, you will generally encounter two scenarios regarding the harness.
You should look for a unit that is either a "Plug and Play" option specifically listed for the 2017 Toyota 86, or a unit that requires a specific wiring harness adapter. The table below outlines the common wiring colors and their functions for this specific application, which helps verify the legitimacy of a wiring kit before purchase.
2017 86 Wiring Color Code Reference
| Wire Color | Function | Notes |
|---|---|---|
| Yellow | Battery Power (Hot) | Constant 12V; use fuse holder |
| Red | Ignition Power (Hot) | 12V when key is on |
| Black | Ground | Must be secured to chassis |
| Orange | Accessory Power | Antenna for after-market radio |
| Grey / White | Left Front Speaker | Verify polarity |
| Grey / Black | Right Front Speaker | Verify polarity | connectivity
Feature Sets To Consider
Not all head units are created equal, and the 2017 86 platform accommodates a wide range of feature sets. Depending on your budget and technical needs, you should prioritize specific functionalities that align with your driving habits.
- Smartphone Integration: As mentioned, CarPlay and Android Auto are non-negotiable for most modern drivers. Ensure the unit supports the latest version of these platforms for compatibility.
- Navigation: While Google Maps and Waze work via smartphone integration, some users prefer a dedicated GPS module or offline maps stored on the unit itself for rural driving.
- Amplifier Compatibility: If you plan to add aftermarket speakers or a subwoofer, ensure the head unit has a dedicated "Amp Remote Turn On" wire (usually blue) to power external amplifiers without draining the battery.
- HD Radio & Podcast Support: For accessing digital广播 and on-demand audio content, verify the unit supports RDS data and common podcast apps.
Installation Considerations
The installation of a 2017 Toyota 86 head unit is generally considered moderate difficulty due to the compact space behind the dashboard and the potential need to modify the center console. While a direct plug-and-play unit might require only a few screws and a wiring tie, certain installations may necessitate the use of a dash kit to fill the gap left by the smaller aftermarket unit. It is highly recommended to disconnect the negative terminal of the battery before beginning the work to prevent short circuits. If you are not comfortable working with vehicle electronics, seeking professional installation ensures that the wiring is secured correctly and that the screen is calibrated properly.
Top Aftermarket Brands
When shopping for a replacement head unit for your 2017 86, several brands stand out in the market for their reliability, user interface, and build quality. Pioneer, Kenwood, and Sony are the industry leaders in in-dash multimedia, offering touch-screen interfaces that rival consumer tablets. Budget-friendly alternatives from brands like Chinese manufacturers on platforms like Amazon or AliExpress can be tempting, but they often lack the longevity, warranty support, and integration testing that major brands provide. Opting for a reputable brand ensures driver safety features are not compromised and that the unit remains compatible with future software updates.
Maximizing Value And Future Proofing
A final aspect to consider when selecting a 2017 Toyota 86 head unit upgrade is how the purchase adds value to the vehicle itself. Since the 86 is a relatively modern classic, investing in a high-quality head unit with physical knobs for volume and track adjustment—rather than only touchscreen controls—can improve usability while driving. Look for units that include Bluetooth audio codecs like aptX for higher fidelity sound over Bluetooth, ensuring that even wireless listening sounds crisp. By choosing a unit with robust connectivity and easy integration, you effectively modernize the cabin technology of your 86, making it more enjoyable for daily driving or spirited weekend runs without sacrificing the original driving dynamics.
