Description
Keep Your Factory Controls When You Upgrade Your Head Unit
Product Overview
The Aerpro ASSZ5C is a vehicle-specific steering wheel control (SWC) interface engineered for the Suzuki Kizashi fitted with a Rockford Fosgate amplified factory audio system. It allows you to install an aftermarket head unit while retaining full use of your factory steering wheel controls no cutting of the factory wiring harness required.
The ASSZ5C uses an analogue interface with a vehicle-specific plug that connects directly into the existing wiring, making installation clean and straightforward. It also retains the factory Rockford Fosgate amplifier and factory USB input (where originally fitted), and provides a speed pulse output feed via the pink wire. A USB retention lead is included in the kit. For a complete installation, Aerpro recommends pairing the ASSZ5C with the APP8 Head Unit Secondary ISO Harness, sold separately.

Frequently Asked Questions
Will this work with any aftermarket head unit?
The head unit must be SWC compatible to work with this interface. Not all aftermarket head units support steering wheel control inputs, so confirm SWC compatibility with your chosen head unit before purchasing.
Do I need to cut any factory wiring?
No. The ASSZ5C uses a vehicle-specific plug that connects directly into the existing factory wiring harness without cutting or splicing.
Does this retain the factory Rockford Fosgate amplifier?
Yes. The ASSZ5C is designed for the Rockford Fosgate amplified variant of the Kizashi and retains the factory amp in the system.
What is the APP8 harness and do I need it?
The Aerpro APP8 is a head unit secondary ISO harness that connects between the aftermarket head unit and the ASSZ5C interface, simplifying the installation. It is sold separately and while not mandatory, Aerpro recommends it for a cleaner install.
Will my steering wheel controls work exactly the same as factory?
Steering wheel control functions may vary from the original OEM setup depending on the aftermarket head unit used. Basic functions such as volume, track skip, and source are typically retained, but advanced OEM functions may not be replicated.
