Double Fakra to DIN aerial adapter (Phantom Power) with Bullet connector (21-139K)

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.

Audi Quadlock CAN steering wheel control interface and audio adapter cable for rear amplified cars (49-AUD-02)

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 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 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.

Universal patch lead for steering control interface (49-025)

Universal patch lead to be used with In car Tec 49 series steering wheel control interfaces. Use for Alpine, Clarion, JVC, Kenwood, Pioneer and Sony head units.

Audi A4 Single/Double DIN car audio radio fascia adapter (50-314)

Audi A4 car radio fascia adapter panel to allow the fitting of an aftermarket Single or Double din car stereo upgrade. The fascia adaptor allows the fitting of an aftermarket radio into the dashboard by matching the shape, style and colour of the original radio. Use the supplied pocket with the fascia adapter to fit a single din radio, or remove the pocket and use the fascia trim only with a 103mm fitting cage to fit a double din after-market head unit. Most aftermarket radios are supplied with a 113mm high cage, because of this an additional 103mm fitting cage is included with this kit.

Double din fitting cage (51-012)

This kit is designed to replace the metal cage kit that is usually supplied with your new aftermarket double din head-unit or navigation system. It is used along with fascias that have 103mm high hole sizes. Complete with fixings to attach to the new car radio body.
