The Audi A3 ’04, top quality equipment features – now available for the compact class as well

details which used to be the sole domain of the more luxurious classes. Such features  include new pre-fitted components for mobile phone installation with voice control, thus allowing drivers to keep both hands on the wheel.

A new dimension in telephone quality for this class of vehicle is achieved by way of echo  compensation and speed-dependent volume control (GALA).

Even the basic sound system offers a centre loudspeaker in the middle of the dash panel to enhance the acoustic effect and natural sound reproduction.

This sound quality can be improved still further with the BOSE sound system, featuring  6-channel actuation and a total output of 222 W.

The standard of control unit networking has also been raised to that of the mid-range  category. The number of interlinked control units is more than twice that of the Audi A3 ’97, thus equipping the compact class with a whole range of top quality functions.
