A CANBUS steering wheel control interface engineered for various Hyundai and Kia vehicles with OEM SPDIF digital amplifiers, the SWKI2C retains factory steering wheel controls and the OEM SPDIF digital amplifier with fader adjustment via the steering wheel controls, and provides reverse trigger, speed pulse, and amp remote outputs with no wire cutting required.
The Aerpro SWKI2C is a CANBUS steering wheel control interface designed for various Hyundai and Kia vehicles fitted with OEM SPDIF digital amplifiers. 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 SWKI2C is compatible with SW-type patch leads (sold separately), supports the OEM phone button when connected to a compatible aftermarket Bluetooth head unit, and retains the OEM SPDIF digital amplifier while allowing fader adjustment via the steering wheel controls.
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. Outputs include reverse trigger, speed pulse (pink), and amp remote. Custom button remapping is available and requires a USB-C cable (sold separately). Installation is simplified when the SWKI2C is paired with the optional Aerpro APP8 Headunit Secondary ISO Harness (sold separately). The aftermarket head unit must be SWC compatible and steering wheel control functions may vary from OEM functions. Use the Aerpro Vehicle Selector to confirm the correct part for your specific vehicle before purchase.
Retains Factory Steering Wheel Controls with Aftermarket Head Unit: The SWKI2C 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.
OEM SPDIF Digital Amplifier Retention with Fader Adjustment: The SWKI2C retains the OEM SPDIF digital amplifier in the vehicle and allows fader adjustment to be performed via the steering wheel controls, preserving the amplified audio system and its adjustability after the head unit upgrade.
CANBUS Interface: The SWKI2C uses a CANBUS interface for direct communication with the vehicle's CANBUS network, enabling reliable integration with the supported Hyundai and Kia SPDIF amplified platforms.
Vehicle-Specific Plug - No Wire Cutting Required: The SWKI2C 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.
OEM Phone Button Support: The SWKI2C 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 SWKI2C. 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: A reverse trigger output enables automatic switching to the reverse camera input on the aftermarket head unit when reverse gear is selected.
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.
Amp Remote Output: An amp remote output is provided for triggering the retained OEM SPDIF digital amplifier when the head unit is powered on.
Compatible with Aerpro APP8 Secondary ISO Harness: The SWKI2C is recommended to be installed with the Aerpro APP8 Headunit Secondary ISO Harness (sold separately), which connects between the aftermarket head unit and the SWKI2C interface for a simplified and complete installation.
