Aerpro ASMC3C Steering Wheel Control Interface for Mercedes with Antenna Retention and Reverse Trigger

A CAN bus steering wheel control (SWC) interface from Aerpro for compatible Mercedes vehicles, the ASMC3C retains factory steering wheel controls and factory antenna, provides reverse trigger and park brake outputs, with a vehicle-specific plug for direct connection without cutting factory wiring and patch lead type H compatibility. A compatible SWC patch lead and APP8 secondary ISO harness are required separately.

Product Overview

The Aerpro ASMC3C is a CAN bus SWC interface engineered for compatible Mercedes 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 ASMC3C retains the factory antenna via the included antenna adaptor, and provides reverse trigger (purple wire) and park brake (green wire) outputs for connection to the aftermarket head unit. Installation is simplified 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 ASMC3C also provides an illumination output.

Note: the ASMC3C does not retain factory amplifier, reverse camera, AUX input, or USB input.

Features & Benefits

Retains Factory Steering Wheel Controls: 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 Mercedes 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 Mercedes wiring connector without cutting, splicing, or permanently modifying the original wiring harness.

Factory Antenna Retention: The ASMC3C includes an antenna adaptor that converts the factory Mercedes antenna connection to a standard DIN plug for connection to the aftermarket head unit.

Reverse Trigger Output (Purple) and Park Brake Output (Green): The ASMC3C provides a reverse trigger output (purple wire) for triggering the aftermarket head unit's reverse camera input, and a park brake output (green wire) for connection to the aftermarket head unit's park brake wire.

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.
