STEERING WHEEL CONTROL INTERFACE TO SUIT MERCEDES - VARIOUS MODELS

The Aerpro CHMC1C Steering Wheel Control Interface (SWC) allows you to upgrade to an aftermarket headunit whilst maintaining use of your factory steering wheel controls. Engineered to suit various Mercedes vehicles with AUDIO 20 headunits and without OEM Amplified sound systems, the steering wheel control interface includes a harness that is fitted with a vehicle specific plug designed to connect directly into the existing wiring in the vehicle with ease, no cutting of the factory wiring harness in the vehicle is required. Installation of the aftermarket headunit is simplified even further when paired with the optional Aerpro APP9 Headunit Secondary ISO Harness & SWC Patch Lead, which connects between the aftermarket headunit and the Aerpro Steering Wheel Control Interface. This interface is CANBUS compatible and provides various outputs including Reverse Trigger, Park Brake, Speed Pulse, Illumination and Telephone Mute.

Please Note:

- A Steering Wheel Control Patch Lead is required to be used in conjunction with this part to enable Steering Wheel Controls to function (sold separately).
