Aerpro SWHY8N Steering Wheel Control Interface Hyundai Various Models OEM Navigation
An analogue steering wheel control interface engineered for various Hyundai vehicles fitted with OEM navigation, the SWHY8N retains factory steering wheel controls with a vehicle-specific plug connection requiring no wire cutting, and provides reverse trigger and illumination outputs.
Product Overview
The Aerpro SWHY8N is an analogue steering wheel control interface designed for various Hyundai vehicles fitted with OEM navigation. It includes a harness fitted with a vehicle-specific plug that connects directly into the existing factory wiring in the vehicle without cutting or modifying the factory harness. The SWHY8N is compatible with SW-type patch leads (sold separately), supports the OEM phone button when connected to a compatible aftermarket Bluetooth head unit, and provides reverse trigger (purple/white wire) and illumination outputs. Voice Assistant support is available; if the steering wheel controls do not include a dedicated Voice Assistant button, the answer button functions as voice support instead, provided the aftermarket head unit and paired phone also support the Voice Assistant feature. Custom button remapping is available and requires a USB-C cable (sold separately).
Installation is simplified when the SWHY8N is paired with the optional Aerpro APP9 Headunit Secondary ISO Harness and SWC Patch Lead (both sold separately). The aftermarket head unit must be SWC compatible and steering wheel control functions may vary from OEM functions. The SWHY8N suits Hyundai vehicles with OEM navigation only. Use the Aerpro Vehicle Selector to confirm the correct part for your specific vehicle before purchase.
Features & Benefits
Retains Factory Steering Wheel Controls with Aftermarket Head Unit: The SWHY8N allows the factory steering wheel audio controls to operate with a compatible aftermarket head unit, maintaining hands-on-the-wheel control without requiring the driver to reach for the head unit directly.
Specific Fitment for Hyundai Models with OEM Navigation: The SWHY8N is engineered specifically for Hyundai vehicles fitted with OEM navigation. Hyundai vehicles without OEM navigation require a different interface. Use the Aerpro Vehicle Selector to confirm the correct part before purchase.
Vehicle-Specific Plug - No Wire Cutting Required: The SWHY8N harness is fitted with a vehicle-specific plug engineered to connect directly into the existing factory wiring in the vehicle. No cutting or modification of the factory wiring harness is required, simplifying installation and preserving the factory wiring integrity.
Analogue Interface Type: The SWHY8N uses an analogue interface type, compatible with the steering wheel control signal architecture used in the supported Hyundai vehicles with OEM navigation.
OEM Phone Button Support: The SWHY8N supports the OEM phone button on the steering wheel when connected to a compatible aftermarket Bluetooth head unit, allowing hands-free call answering and ending from the steering wheel controls.
Voice Assistant Support: Voice Assistant support is available through the SWHY8N. If the steering wheel does not include a dedicated Voice Assistant button, the answer button functions as voice support instead. The aftermarket head unit and paired phone must also support the Voice Assistant feature for this to operate.
Reverse Trigger Output (Purple/White): The SWHY8N provides a reverse trigger output via a purple/white wire, enabling automatic switching to the reverse camera input on the aftermarket head unit when reverse gear is selected.
Illumination Output: An illumination output is provided, allowing the aftermarket head unit to automatically adjust its display brightness in response to the vehicle's instrument illumination signal.
Custom Button Remapping Available: The SWHY8N supports optional custom button remapping to customise the steering wheel control button configuration. Remapping requires a USB-C cable (sold separately).
Compatible with Aerpro APP9 Secondary ISO Harness: The SWHY8N is recommended to be installed with the Aerpro APP9 Headunit Secondary ISO Harness and SWC Patch Lead (both sold separately) for a simplified and complete installation.
