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.
