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 amplified speakers. All Audi TT 8J model cars have fully amplified audio systems. 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.
This interface needs to be used with a 49- series patch lead to suit the make of head unit that is being fitted.
