Aerpro SWSZ3C Suzuki Steering Wheel Control SWC Interface

Keep Your Steering Wheel Controls When You Upgrade Your Head Unit

The Aerpro SWSZ3C is a plug-and-play steering wheel control (SWC) interface engineered specifically for various Suzuki vehicles. It bridges your factory steering wheel controls with an aftermarket head unit — so you don't lose the convenience of volume, track, and phone controls when you upgrade your in-car entertainment.

Designed with the installer in mind, the SWSZ3C uses a vehicle-specific plug that connects directly into your Suzuki's existing wiring loom. There's no cutting of the factory harness required. The analogue interface supports OEM phone button and voice assistant button functionality when paired with a compatible Bluetooth-enabled aftermarket head unit, making it one of the most complete SWC interfaces available for Suzuki applications. For an even cleaner install, it pairs directly with the Aerpro APP8 Secondary ISO Harness (sold separately).

Please note: SWC interfaces vary between Suzuki models. Use the Aerpro Vehicle Selector to confirm the correct part for your specific vehicle. Aftermarket head unit must be SWC compatible. Steering wheel control functions may vary from OEM factory functions.
