Aerpro SWMC15C SWC Interface Mercedes Sprinter 2018-2020 CANBUS

Aerpro SWMC15C CANBUS Steering Wheel Control Interface for Mercedes Sprinter 2018 to 2020 with Multiple Signal Outputs

The Aerpro SWMC15C is a CANBUS steering wheel control (SWC) interface engineered specifically for Mercedes Sprinter vehicles from 2018 to 2020. It retains factory steering wheel controls after an aftermarket head unit is installed and provides reverse trigger, park brake, speed pulse and illumination output feeds making it one of the more feature-complete SWC interfaces in the Aerpro range. Phone button functionality is supported with compatible aftermarket Bluetooth head units. No wire cutting is required. Voice assistant button support is not available.

Product overview

The SWMC15C uses CANBUS integration to communicate with the Mercedes Sprinter's vehicle data network, reading steering wheel control inputs and translating them to the aftermarket head unit without requiring additional CANBUS modules. This native CANBUS compatibility means the interface works directly with the Sprinter's factory wiring architecture from 2018 to 2020 without modification.

In addition to steering wheel control retention, the SWMC15C provides four signal outputs that expand what the aftermarket head unit can do in the vehicle. The reverse trigger output (purple wire) sends a signal when reverse is engaged, activating a connected reversing camera. The park brake output (green wire) confirms park brake status. The speed pulse output (pink wire) provides vehicle speed data for head units that use it for navigation or audio functions. The illumination output (orange wire) sends a signal when the vehicle lights are on, dimming the head unit display to suit. OEM amplified system retention and amplifier remote output are not supported. Pairing with the Aerpro APP8 Headunit Secondary ISO Harness (sold separately) is recommended for a streamlined installation.

Features and benefits

CANBUS integration, no additional modules required: Native CANBUS compatibility reads the Sprinter's steering wheel control inputs directly from the vehicle data network, eliminating the need for an additional CANBUS decoding module.

Retains factory steering wheel controls: Allows the factory steering wheel audio controls to function with an aftermarket head unit, keeping hands on the wheel and eyes on the road.

Phone button support with compatible Bluetooth head units: Phone button functionality is retained when connected to a compatible aftermarket Bluetooth head unit.

Reverse trigger output (purple wire): Sends a signal when reverse gear is engaged, activating a connected reversing camera or triggering the head unit's reverse camera input.

Park brake output (green wire): Provides a park brake status signal for the aftermarket head unit.

Speed pulse output (pink wire): Provides vehicle speed data for head units that use speed pulse input for navigation or audio functions.

Illumination output (orange wire): Sends a signal when the vehicle lights are on, allowing the head unit to dim its display in line with the ambient lighting.

Vehicle-specific plug, no wire cutting required: The harness includes a plug designed to connect directly into the existing Mercedes Sprinter wiring without cutting or modifying the factory loom.

No OEM amplified system retention: The SWMC15C does not retain the OEM amplified audio system. Confirm this suits your Sprinter's audio configuration before purchasing.

Custom button remapping available: Default button configuration can be remapped to suit different aftermarket head unit button assignments. Requires a USB-C cable (sold separately) and Aerpro remapping instructions.

Compatible with Aerpro APP8 ISO harness: Pairing with the Aerpro APP8 Headunit Secondary ISO Harness (sold separately) simplifies the connection between the SWMC15C and the aftermarket head unit.

Frequently asked questions

What does CANBUS mean and why does it matter for this interface? CANBUS is a vehicle communication network that allows different electronic modules to share data. The SWMC15C reads steering wheel control inputs directly from the Sprinter's CANBUS network, which means no additional CANBUS decoding module is required. This simplifies installation and ensures reliable communication with the vehicle's factory systems.

What are the output wires on the SWMC15C used for? The SWMC15C provides four signal outputs in addition to the steering wheel control connection. The purple wire sends a reverse trigger signal when reverse gear is engaged. The green wire provides park brake status. The pink wire provides vehicle speed pulse data. The orange wire sends an illumination signal when the vehicle lights are on. Each output connects to the corresponding input on the aftermarket head unit where applicable.

Does the SWMC15C support phone buttons on the steering wheel? Yes, with a compatible aftermarket Bluetooth head unit. Phone button functionality is retained when the head unit supports Bluetooth phone integration. Confirm this with the head unit specifications before purchasing.

Do I need to cut any factory wiring to install the SWMC15C? No. The SWMC15C harness includes a vehicle-specific plug that connects directly into the existing Mercedes Sprinter wiring without any cutting or modification to the factory loom.

What is the Aerpro APP8 and do I need it? The Aerpro APP8 is a headunit secondary ISO harness that connects between the aftermarket head unit and the SWMC15C interface, simplifying the overall installation. It is sold separately and is recommended but not mandatory for the SWMC15C to function.
