Description
Full Factory Feature Retention When You Upgrade Your Honda's Head Unit
Product Overview
The Aerpro ASMB11C is a CAN bus steering wheel control (SWC) interface engineered for a range of Honda vehicles. It allows you to install an aftermarket head unit while retaining your factory steering wheel controls, Rockford Fosgate amplified sound system, reverse camera (including 360-degree where fitted), factory antenna, AUX input, and dual USB inputs all without cutting the factory wiring harness.
The ASMB11C connects via a vehicle-specific plug that drops straight into the existing wiring, and the kit includes a reverse camera retention adaptor (360-degree compatible) and AUX and USB retention leads. It provides reverse trigger (purple) and park brake (green) output feeds for compatible head units, along with an illumination output. For a complete installation, Aerpro recommends pairing the ASMB11C with the APP8 Head Unit Secondary ISO Harness, sold separately.
