The Aerpro CHTO15C Steering Wheel Control Interface (steering wheel control) allows you to upgrade to an aftermarket headunit whilst maintaining use of your factory steering wheel controls. Engineered to suit various Toyota vehicles with 28 pin connector, 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.

This interface also includes an antenna adaptor, reverse camera retention adaptor and USB retention lead. Installation of the aftermarket headunit is simplified even further when paired with the optional Aerpro APP9 Headunit secondary ISO harness and steering wheel control patch lead, which connects between the aftermarket headunit and the Aerpro Steering Wheel Control Interface. This interface retains the factory antenna, USB input, AUX input and reverse camera when connected to compatible aftermarket headunits. It also provides outputs for reverse trigger, park brake and speed pulse signal.
