A CANBUS steering wheel control interface engineered for various Toyota vehicles with OEM amplified systems and 360-degree cameras, the SWTO20C retains factory steering wheel controls, OEM amplifier, OEM 360-degree reverse camera, OEM USB input, and OEM AUX input, and provides reverse trigger, park brake, and speed pulse outputs with no wire cutting required.
The Aerpro SWTO20C is a CANBUS steering wheel control interface designed for various Toyota vehicles fitted with OEM amplified systems and 360-degree cameras. It includes a harness fitted with a vehicle-specific plug that connects directly into the existing factory wiring in the vehicle without cutting or modifying the factory harness. No additional modules are required for CANBUS vehicles.
The SWTO20C is compatible with SW-type patch leads (sold separately), supports the OEM phone button when connected to a compatible aftermarket Bluetooth head unit, and retains the OEM amplifier, OEM 360-degree reverse camera, OEM USB input, and OEM AUX input when connected to a compatible aftermarket head unit. OEM AUX and USB retention requires the aftermarket head unit to have rear USB and AUX inputs. OEM 360-degree camera retention applies only if the vehicle was originally fitted with a factory 360-degree camera, and the aftermarket head unit must have an RCA camera input. For amplified vehicles, fade is not supported. Outputs include reverse trigger (purple/white), park brake (green), and speed pulse (pink).
Custom button remapping is available and requires a USB-C cable (sold separately). Installation is simplified when the SWTO20C is paired with the optional Aerpro APP8 Headunit Secondary ISO Harness (sold separately). The aftermarket head unit must be SWC compatible and steering wheel control functions may vary from OEM functions. Use the Aerpro Vehicle Selector to confirm the correct part for your specific vehicle before purchase.
Retains Factory Steering Wheel Controls with Aftermarket Head Unit: The SWTO20C allows the factory steering wheel audio controls to operate with a compatible aftermarket head unit, maintaining hands-on-the-wheel control without requiring the driver to reach for the head unit directly.
CANBUS Interface - No Additional Modules Required: The SWTO20C uses CANBUS integration for direct communication with the vehicle's CANBUS network, eliminating the need for additional interface modules in compatible Toyota vehicles.
OEM Amplifier Retention: The SWTO20C retains the OEM amplified system in the vehicle when connected to a compatible aftermarket head unit. Fade is not supported for amplified vehicles.
OEM 360-Degree Reverse Camera Retention: The SWTO20C retains the factory 360-degree reverse camera when connected to a compatible aftermarket head unit with an RCA camera input. Retention applies only if the vehicle was originally fitted with a factory 360-degree camera system.
OEM USB Input Retention: The SWTO20C retains the OEM USB input when connected to a compatible aftermarket head unit with a rear USB input, preserving the factory USB connectivity after the head unit upgrade.
OEM AUX Input Retention: The SWTO20C retains the OEM AUX input when connected to a compatible aftermarket head unit with a rear AUX input, preserving the factory AUX connectivity after the head unit upgrade.
Vehicle-Specific Plug - No Wire Cutting Required: The SWTO20C harness is fitted with a vehicle-specific plug engineered to connect directly into the existing factory wiring in the vehicle. No cutting or modification of the factory wiring harness is required, simplifying installation and preserving the factory wiring integrity.
OEM Phone Button Support: The SWTO20C supports the OEM phone button on the steering wheel when connected to a compatible aftermarket Bluetooth head unit, allowing hands-free call answering and ending from the steering wheel controls.
Reverse Trigger Output (Purple/White): A reverse trigger output via a purple/white wire enables automatic switching to the reverse camera input on the aftermarket head unit when reverse gear is selected.
Park Brake Output (Green): A park brake output is provided via a green wire, supplying the park brake signal required by compatible aftermarket head units for safety feature operation.
Speed Pulse Output (Pink): A speed pulse output is provided via a pink wire for aftermarket head units that require a vehicle speed signal for navigation or speed-dependent volume functions.
Compatible with Aerpro APP8 Secondary ISO Harness: The SWTO20C is recommended to be installed with the Aerpro APP8 Headunit Secondary ISO Harness (sold separately), which connects between the aftermarket head unit and the SWTO20C interface for a simplified and complete installation.
