TT (8J) 2006-2014
All Mk II Audi TTs are fitted with a fully amplified audio system. This will either be the standard or BOSE amplified system, distinguishable by the BOSE logos on the speaker grills.
The amplifier is housed in the near side rear quarter panel.
The amplifier in the TT is normally turned on with a 12V switch signal. The below image shows the pin-out with DSP EIN denoting the amp turn position.
Although the front speakers are marked on the diagram, The wires are not present in the Quadlock wiring loom.
Vehicles with the factory navigation system use a CANbus signal to turn the amplifier on instead. Using our CANbus steering control interface will turn on the amplifier. Alternatively, the turn on method can be changed to using the 12V switch pin position using VAG-COM VCDS.
If your original plug looks like this you need AIS2265
