Plug-and-play SWC retention harness engineered to keep your Nissan's steering wheel controls fully functional when upgrading to an aftermarket head unit, no cutting, no compromising.
The Car Audio Connect HNS9K is a purpose-built wiring harness designed to retain factory steering wheel control (SWC) functionality across a wide range of Nissan vehicles when installing an aftermarket head unit. Without a proper SWC harness, upgrading your stereo typically means losing the ability to control audio functions from the steering wheel a frustrating and potentially unsafe compromise. The HNS9K eliminates this problem entirely with a direct plug-and-play connection that interfaces seamlessly with the factory Nissan wiring harness, requiring no cutting or splicing.
Compatible with a broad spectrum of Nissan models spanning from 1997 to 2015 including the popular 350Z, Navara D22, Patrol GU, Skyline, and X-Trail the HNS9K is engineered to work with aftermarket head units from Alpine, JVC, Kenwood, Nakamichi, Pioneer, Sony, and other leading brands. Whether you're upgrading a daily driver or a weekend 4WD, the HNS9K ensures your steering wheel controls work exactly as intended with your new stereo.
Steering Wheel Control Retention: The primary function of the HNS9K is to retain full factory SWC functionality after an aftermarket head unit installation, ensuring volume, track, and call controls remain fully operable directly from the steering wheel, improving driver safety and convenience.
Plug and Play Installation: Designed for direct connection to the factory Nissan wiring harness with no cutting or splicing required, the HNS9K significantly simplifies the installation process and reduces the risk of wiring errors during head unit upgrades.
Broad Vehicle Compatibility: Engineered to suit nine distinct Nissan model lines spanning nearly two decades, from the 1997 Patrol GU through to the 2015 Navara D22, making it a versatile solution for Nissan owners and professional installers alike.
Wide Head Unit Brand Support: Compatible with aftermarket stereos from Alpine, JVC, Kenwood, Nakamichi, Pioneer, Sony, and other brands, giving installers and end users maximum flexibility in head unit selection without sacrificing factory SWC functionality.

Goes Well With:
What steering wheel controls does the HNS9K retain?
The HNS9K is designed to retain the factory steering wheel audio controls included in compatible Nissan vehicles. This typically covers volume up/down, track skip forward/back, and source/mode selection. The exact controls retained will depend on the original factory SWC configuration of your specific Nissan model and year.
Does the HNS9K work with all aftermarket head units?
The HNS9K is compatible with aftermarket head units from Alpine, JVC, Kenwood, Nakamichi, Pioneer, Sony, and other brands that support SWC input. However, some head units may require an additional SWC interface or patch lead to fully decode and map the steering wheel control signals. Check your chosen head unit's SWC compatibility prior to installation.
Do I need any additional parts to complete my Nissan head unit install?
In most cases, you will also need a vehicle-specific primary wiring harness, a fascia/dash kit to suit your Nissan model, and potentially an antenna adaptor. A separate SWC patch lead may also be required depending on your chosen aftermarket head unit. We carry a full range of Nissan installation accessories, contact us if you need help selecting the right parts for your vehicle.
Is the HNS9K compatible with the Nissan Navara D40 or newer models?
No. The HNS9K is specifically listed for the Nissan Navara D22 (2006–2015). It is not confirmed compatible with the D40 or later Navara variants, or with Nissan models released after 2015. For newer Nissan vehicles, please contact our team to confirm the correct harness for your application.
Is professional installation recommended for the HNS9K?
While the HNS9K is designed for plug-and-play installation and is suitable for confident DIY installers, professional installation by a qualified car audio technician is always recommended. A professional installer will ensure correct harness connection, proper SWC mapping, and that all factory functions are verified operational after the head unit upgrade.
