Retrofitting radio systems
The connectors on the factory-installed radio
wiring harness are designed for genuine Audi
radios.
Radios with different types of connectors must
be installed using adapter wires.
CAUTION!
When connecting the vehicle speed sensor
signal wire (on radios with the GALA
function), take particular care to avoid short
circuits, which could result in vehicle
malfunctions (e.g. in the engine management
system).
Vehicle malfunctions may also occur if the
vehicle speed sensor signal wire is connected
to radios supplied by other manufacturers.
If a non-stock radio is installed ("Concert" m.y.
1998 ) it can have a negative effect on the
antenna amplifier. The original Audi radio units
supply power to the antenna amplifier through
the center wire of the HF cable.
Retrofitting CD systems
The wiring for the CD changer is installed in the
