Aerpro ASSU3C Steering Wheel Control Interface for Subaru with Antenna Adaptor
A CAN bus steering wheel control (SWC) interface from Aerpro for compatible Subaru vehicles, the ASSU3C allows factory steering wheel controls to be retained when installing an aftermarket head unit, with a vehicle-specific plug for direct connection without cutting factory wiring, an antenna adaptor for factory antenna retention, and patch lead type H compatibility. A compatible SWC patch lead and APP8 secondary ISO harness are required separately.
Product Overview
The Aerpro ASSU3C is a CAN bus SWC interface engineered for compatible Subaru vehicles, designed to retain factory steering wheel control function during aftermarket head unit installation. The vehicle-specific plug connects directly into the existing wiring in the vehicle with no cutting or modification to the factory harness required. The included antenna adaptor converts the factory Subaru antenna plug to a standard DIN plug suitable for aftermarket head units. Installation is simplified further when paired with the Aerpro APP8 Secondary ISO Harness (sold separately). A compatible type H SWC patch lead is required separately for SWC function.
The ASSU3C provides illumination output but does not provide reverse trigger, park brake, speed pulse, amp remote, or telephone mute outputs, and does not retain factory amplifier, reverse camera, AUX input, or USB input. Steering wheel control functions may vary from OEM functions depending on the aftermarket head unit used.
Features & Benefits
Retains Factory Steering Wheel Controls: The ASSU3C enables retention of factory steering wheel audio controls when upgrading to a compatible aftermarket head unit, keeping hands on the wheel and eyes on the road.
CAN Bus Interface: CAN bus communication decodes the factory steering wheel control signals for compatibility with aftermarket head units when paired with a compatible type H SWC patch lead.
Vehicle-Specific Plug - No Cutting of Factory Wiring: The harness plugs directly into the factory Subaru wiring connector behind the head unit without requiring cutting, splicing, or permanent modification of the factory wiring harness.
Antenna Adaptor Included: The included antenna adaptor converts the factory Subaru antenna connection to a standard DIN plug for connection to the aftermarket head unit without additional hardware.
Illumination Output: Provides an illumination output for connection to the aftermarket head unit's illumination wire.
Recommended Pairing with Aerpro APP8: Installation is simplified when paired with the Aerpro APP8 Head Unit Secondary ISO Harness (sold separately), which connects between the aftermarket head unit and the SWC interface.
