An analogue steering wheel control interface engineered for various Citroen, Mitsubishi, and Peugeot vehicles without OEM amplified sound systems, the SWMB2C retains factory steering wheel controls and OEM AUX input with a vehicle-specific plug connection that requires no cutting of the factory wiring harness.
The Aerpro SWMB2C is an analogue steering wheel control interface designed for various Citroen, Mitsubishi, and Peugeot vehicles without OEM amplified sound systems. 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 SWMB2C is compatible with SW-type patch leads (sold separately) and supports the OEM phone button when connected to a compatible aftermarket Bluetooth head unit. OEM AUX retention is also supported when the aftermarket head unit has a rear RCA AUX input.
Voice Assistant support is available; if the steering wheel controls do not include a dedicated Voice Assistant button, the answer button functions as phone 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).
Phone buttons on steering wheels do not support Sony aftermarket head unit models: the Answer button functions as Mute and the Hang Up button functions as Source on Sony units. Alpine, Clarion, Kenwood, Pioneer, and Zenec head units support the phone button. Installation is simplified when the SWMB2C 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. The SWMB2C is not suitable for OEM amplified vehicles. 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 SWMB2C 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 SWMB2C 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 AUX Input Retention: The SWMB2C supports OEM AUX retention when connected to a compatible aftermarket head unit with a rear RCA AUX input, retaining the factory AUX input functionality after the head unit upgrade.
Analogue Interface Type: The SWMB2C uses an analogue interface type, compatible with the steering wheel control signal architecture used in the supported Citroen, Mitsubishi, and Peugeot vehicles.
OEM Phone Button Support: The SWMB2C supports the OEM phone button on the steering wheel when connected to a compatible aftermarket Bluetooth head unit. Phone button support is available on Alpine, Clarion, Kenwood, Pioneer, and Zenec head units. On Sony head units, the Answer button functions as Mute and the Hang Up button functions as Source.
Voice Assistant Support: Voice Assistant support is available through the SWMB2C. If the steering wheel does not include a dedicated Voice Assistant button, the answer button functions as phone support instead. The aftermarket head unit and paired phone must also support the Voice Assistant feature for this to operate.
Custom Button Remapping Available: The SWMB2C supports optional custom button remapping to customise the steering wheel control button configuration. Remapping requires a USB-C cable (sold separately).
Not Suitable for OEM Amplified Vehicles: The SWMB2C is not suitable for Citroen, Mitsubishi, or Peugeot vehicles fitted with OEM amplified sound systems. Use the Aerpro Vehicle Selector to confirm compatibility with your specific vehicle before purchase.
Compatible with Aerpro APP8 Secondary ISO Harness: The SWMB2C is recommended to be installed with the Aerpro APP8 Headunit Secondary ISO Harness (sold separately), which connects between the aftermarket head unit and the SWMB2C interface for a simplified and complete installation.
