Aerpro SWNI9C Steering Wheel Control Interface Nissan Without OEM Navigation
Upgrade to an aftermarket head unit while maintaining factory steering wheel controls, USB functionality, and reverse camera operation with professional CANBUS integration designed specifically for Nissan vehicles.
Product Overview
The Aerpro SWNI9C Steering Wheel Control Interface is a professional CANBUS integration solution engineered specifically for various Nissan vehicles without OEM Navigation head units, enabling seamless aftermarket head unit upgrades while maintaining factory steering wheel control functionality. This intelligent interface allows drivers to retain the convenience and safety of factory steering wheel buttons for controlling volume, track skip, source selection, and phone functions on compatible aftermarket head units without losing the hands-on-wheel operation that's essential for safe driving. The interface features a vehicle-specific plug that connects directly into existing Nissan wiring without requiring cutting or splicing of factory harnesses, preserving vehicle integrity and enabling complete reversibility if needed. Beyond steering wheel control retention, the SWNI9C provides comprehensive integration including OEM reverse camera retention when equipped and connected to compatible aftermarket AV head units, OEM USB input retention when vehicle is equipped and aftermarket head unit is compatible, and critical vehicle data outputs including reverse trigger (purple/white wire), park brake signal (green wire), and speed pulse output (pink wire) for advanced head unit features. Installation is further simplified when paired with the optional Aerpro APP8 Headunit ISO Harness which connects between the aftermarket head unit and the steering wheel control interface for complete plug-and-play installation. The CANBUS-compatible design eliminates the need for additional modules or interfaces, streamlining installation and reducing complexity while ensuring reliable long-term operation.
Features & Benefits
Factory Steering Wheel Control Retention: Maintains full functionality of factory steering wheel buttons for controlling aftermarket head unit functions including volume adjustment, track skip, source selection, and phone operation, increasing driver safety by allowing hands to remain on the steering wheel and eyes on the road rather than reaching for head unit controls during driving.
OEM Phone Button Support: Supports factory phone button functionality when connected to compatible aftermarket Bluetooth head units, enabling hands-free call answering, call rejection, and voice command activation directly from steering wheel controls without requiring separate Bluetooth control modules or compromising the integrated experience Nissan owners expect from modern vehicles.
OEM Reverse Camera Retention: Retains factory reverse camera functionality when vehicle is equipped with OEM reverse camera and aftermarket head unit features RCA camera input, automatically displaying rear view on aftermarket head unit screen when reverse gear is engaged, preserving essential parking safety features without requiring aftermarket camera installation or losing factory camera quality.
OEM USB Input Retention: Maintains factory USB port functionality when vehicle is equipped with OEM USB and aftermarket head unit features rear USB input compatibility, allowing continued use of factory USB location for device charging and media playback without losing convenient factory connection points or requiring aftermarket USB extension cables.
CANBUS Integration Technology: Advanced CANBUS-compatible design interfaces directly with Nissan's vehicle communication network without requiring additional modules, providing seamless integration that reads vehicle data accurately, responds to steering wheel inputs instantly, and maintains reliable operation without the complexity and failure points associated with multi-module installations.
Critical Vehicle Data Outputs: Provides essential output feeds including reverse trigger signal (purple/white wire) for automatic camera activation, park brake signal (green wire) for video-in-motion bypass systems, and speed pulse output (pink wire) for navigation systems and speed-dependent features, enabling full functionality of advanced aftermarket head unit capabilities.
Plug-and-Play Installation: Fitted with vehicle-specific plug designed to connect directly into existing Nissan wiring without cutting factory harnesses, preserving vehicle integrity, maintaining warranty compliance, enabling complete installation reversibility, and reducing installation time compared to universal interfaces requiring wire splicing or soldering that can introduce reliability issues and complicate future service.

Compatible With
The Aerpro SWNI9C steering wheel control interface is specifically designed for various Nissan vehicle models without OEM Navigation head units. Specific vehicle compatibility varies by model year and factory equipment configuration – use the Aerpro Vehicle Selector tool to verify compatibility with your specific Nissan model and year before purchasing. This interface is NOT compatible with Nissan vehicles equipped with factory navigation systems, which require different interface solutions. Compatible with aftermarket head units from all major manufacturers including Pioneer, Kenwood, Sony, Alpine, JVC, and others, provided the aftermarket head unit features steering wheel control compatibility (most modern aftermarket head units support SWC through standard protocols). Steering wheel control functions may vary from OEM functions depending on aftermarket head unit programming capabilities and available button mapping options. OEM USB retention requires both vehicle to be equipped with factory USB input AND aftermarket head unit to feature rear USB input compatibility – basic head units without USB inputs cannot utilize this retention feature. OEM reverse camera retention requires both vehicle to be equipped with factory reverse camera AND aftermarket head unit to feature RCA camera input (typically found on AV head units with video capability) – audio-only head units cannot display camera feed. The reverse trigger, park brake, and speed pulse outputs integrate with compatible aftermarket head units and navigation systems that utilize these signals for automatic camera activation, video-in-motion control, and speed-dependent navigation features. Installation is significantly simplified when paired with Aerpro APP8 series headunit ISO harnesses which provide standardized ISO connections between interface and aftermarket head unit, though direct wiring to head unit is possible for experienced installers. Not compatible with Nissan vehicles equipped with Bose or other factory amplified audio systems requiring separate amplifier retention solutions.
Frequently Asked Questions
Q: How do I know if this interface fits my Nissan?
A: The SWNI9C is designed for various Nissan models without OEM Navigation. Use the Aerpro Vehicle Selector tool to confirm compatibility with your specific Nissan model and year. This interface is NOT compatible with Nissan vehicles that have factory navigation systems, which require different interfaces.
Q: Will all my steering wheel buttons work with any aftermarket head unit?
A: Aftermarket head unit must be SWC (steering wheel control) compatible, which most modern units are. However, steering wheel control functions may vary from OEM functions depending on the head unit's programming capabilities. Some advanced functions may not be supported by all aftermarket head units.
Q: Does this interface retain my factory reverse camera?
A: Yes, if your Nissan is equipped with a factory reverse camera AND your aftermarket head unit has an RCA camera input (common on AV head units with video capability). Audio-only head units without video capability cannot display the camera feed even though the interface supports camera retention.
Q: Will my factory USB port still work after installing an aftermarket head unit?
A: Yes, if your Nissan is equipped with factory USB AND your aftermarket head unit has rear USB input compatibility. The interface retains the factory USB connection, but the aftermarket head unit must support rear USB input to utilize this feature.
Q: Do I need any additional harnesses or modules for installation?
A: The SWNI9C is CANBUS compatible and doesn't require additional modules. However, installation is significantly simplified when paired with an Aerpro APP8 series headunit ISO harness (sold separately), which provides standardized connections between the interface and your aftermarket head unit.
