The Aerpro CHAD3C Steering Wheel Control Interface (SWC) allows you to upgrade to an aftermarket head unit whilst maintaining use of your factory steering wheel controls. Engineered to suit various Audi models with Concert, Symphony or Chorus OEM head units & Quadlock (40 Way) Connector, the interface will also maintain OEM amplified Bose systems, non-digital amplified systems (the aftermarket head unit requires front & rear RCA pre-outs).

Installation of the aftermarket head unit is simplified even further when paired with the optional Aerpro APP9 Head unit Secondary ISO Harness & SWC Patch Lead, which connects between the aftermarket head unit 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 Amp Remote.
