Audi's Multi Media Interface system, which is used to control many of the car's functions, has also been updated.
It continues to feature a central knob and buttons to change between and select functions.
Special features include a CD, DVD and sat-nav system, which is combined with a 40GB hard drive that can be used to store MP3 files and up to 2000 addresses.
The sat-nav can also feature landscapes in topographical relief, including three-dimensional images of landmark buildings.
The seven-inch sat-nav screen can also be specified with a TV tuner, so that it can show digital television programmes.
