This tailored kit is designed specifically for Audi A4 (B7) vehicles with steering wheel controls and rear amplified audio systems. The supplied CANbus steering wheel control interface allows the Pioneer SPH-PF97BT to work seamlessly with the factory buttons, while also providing the correct ignition feed and amplifier turn-on signal. A built-in high-to-low level adapter ensures the new stereo integrates cleanly with the rear amplifier and subwoofer, delivering high-quality audio without distortion.

Also included is a Double Fakra to DIN aerial adapter with 12V phantom power, ensuring strong radio reception by powering the factory amplified antenna system. Completing the kit is a bespoke 9-inch fascia adapter, designed to securely house the Pioneer stereo while retaining the OEM look of the Audi A4 dashboard.

• Quadlock CAN Steering Wheel Control Interface and Audio Adapter Cable for Rear Amplified Cars
• Double Fakra to DIN Aerial Adapter (Phantom Power) with Bullet Connector

Fascia Adapter Panel

Designed specifically for the Audi A4 (B7), this fascia is engineered for a simple, seamless installation of the Pioneer 9” stereo. Built as a bespoke fit for vehicles in the application list, it adapts the dashboard aperture after removing the factory stereo to accept a universally mounted 4-screw head unit. This ensures compatibility with most aftermarket stereos while retaining the original OEM-style appearance of the dashboard.

Quadlock CAN Steering Wheel Control Interface and Audio Adapter Cable for Rear Amplified Cars

This cable adapts from the original connector in the car, known as a quadlock, to standard aftermarket connectors for the new stereo, known as ISO connectors. The CANbus steering wheel control interface will retain the use of the original radio controls on the steering wheel with an aftermarket stereo. The CANbus interface generates a key present ignition supply to the new stereo, this means the stereo will turn on with the first click of the key and stay on until the key is removed from the ignition barrel. The interface also generates speed pulse, reverse gear and handbrake output signals, these are used when installing multimedia, navigation units and reverse cameras. This interface is built into the Quadlock to ISO harness adapter.

Quadlock to ISO cable also has a built in high to low level adapter for the rear amplified speakers.  The adapter allows the new stereo to work with the original amplifier which drives all the speakers in the car and the subwoofer. The high to low level adapter gives a much cleaner audio signal to the amplifier compared to using line output phono leads.

Double Fakra to DIN Aerial Adapter (Phantom Power) with Bullet Connector

Double Fakra to DIN antenna adapter cable with 12v phantom power from a male bullet connection. This antenna adapter cable adapts from the original Double Fakra connector in the vehicle to a standard aftermarket radio DIN antenna connection for the fitting of a stereo upgrade.

Pioneer Patch Lead for Steering Control Interface

Connects the Pioneer SPH-PF97BT to the steering wheel control adapter.
