Aerpro SWHY8C Steering Wheel Control Interface Hyundai Various Models
An analogue steering wheel control interface engineered for various non-amplified Hyundai vehicles, the SWHY8C retains factory steering wheel controls with a vehicle-specific plug connection that requires no cutting of the factory wiring harness, and provides a speed pulse output.
Product Overview
The Aerpro SWHY8C is an analogue steering wheel control interface designed for various non-amplified Hyundai vehicles. 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 SWHY8C 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 a speed pulse output via a pink wire. Voice Assistant support is available; if the steering wheel controls do not include a dedicated Voice Assistant button, the answer button functions as phone answer 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 SWHY8C is paired with the optional Aerpro APP8 Headunit Secondary ISO Harness (sold separately), which connects between the aftermarket head unit and the SWHY8C interface. The aftermarket head unit must be SWC compatible and steering wheel control functions may vary from OEM functions. The SWHY8C suits non-amplified vehicles. 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 SWHY8C 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.
Vehicle-Specific Plug - No Wire Cutting Required: The SWHY8C 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 SWHY8C uses an analogue interface type, compatible with the steering wheel control signal architecture used in the supported non-amplified Hyundai vehicles.
OEM Phone Button Support: The SWHY8C 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 SWHY8C. If the steering wheel does not include a dedicated Voice Assistant button, the answer button functions as phone answer instead. The aftermarket head unit and paired phone must also support the Voice Assistant feature for this to operate.
Speed Pulse Output (Pink): A speed pulse output is provided via a pink wire for aftermarket head units that require a vehicle speed signal for navigation or speed-dependent volume functions.
Suits Non-Amplified Vehicles: The SWHY8C is designed for non-amplified Hyundai vehicles. Vehicles with OEM amplified sound systems require a different interface.
Custom Button Remapping Available: The SWHY8C supports optional custom button remapping to customise the steering wheel control button configuration. Remapping requires a USB-C cable (sold separately).
Compatible with Aerpro APP8 Secondary ISO Harness: The SWHY8C is recommended to be installed with the Aerpro APP8 Headunit Secondary ISO Harness (sold separately), which connects between the aftermarket head unit and the SWHY8C interface for a simplified and complete installation.
