This head unit fitting kit includes:

Audi quadlock to ISO radio adapter cable with CANbus ignition interface

This Quadlock to ISO adapter cable with CANbus ignition 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 ignition 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. This interface is built into the Quadlock to ISO harness adapter so installation is plug and play.

The plug and play Quadlock to ISO cable also has a built in high to low level adapter for the 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 adjustable high to low level adapter gives a much cleaner audio signal to the amplifier compared to using line output phono leads.

Antenna adapter cable

Double moulded Fakra Aerial adapter cable for European cars that have amplified original antennas. Use with cars that have twin antenna both requiring power. This cable converts the cars existing ISO aerial plug to an aftermarket DIN type used by most car radio manufacturers. Will also provide a power feed to give 12 volt from the car radio to the cars amplified antenna.

9 Inch Fascia adapter panel

Custom-designed for the Audi A3 (8P) facelift (2006–2013), this fascia enables seamless installation of a universally mounted 4-screw stereo. It converts the factory aperture while maintaining a clean, OEM-style dashboard appearance.
