Audi TT 8J mk2

Production years 2006-2014

The differences from the first to second generation Audi TT are easy to see. Updated vehicle styling and a larger than double din radio replaces the single din sized radio from the older model.

Many second generation TTs have the high end Bose amplified audio system, although many TTs don't have the Bose branded system, all second generation TTs have fully amplified audio systems, unlike other Audi cars like the A3 and A4 which have rear amplified systems as standard.

The amplifier in the TT is turned on with a 12V switch signal, cars with original navigation systems use a CANbus turn on signal for the amplifier instead. Using our CANbus steering control interface this will turn on the amplifier. It is also possible to change the amp turn on back to a 12V signal using VAG-COM VCDS.

The DSP EIN position is the amplifier turn on signal.

Although the front speakers are marked on the diagram, the wires are not present in the vehicle.
