1.1.1 Notes on radio service installation
• Radios with different types of connector must be installed us‐
ing adapter wires.
• When connecting vehicle speed signal wire (GALA function),
take particular care to avoid short circuits as otherwise vehicle
malfunctions could occur (e.g. engine management system).
• Vehicle malfunctions may also occur if the vehicle-speed sig‐
nal wire is connected to radios supplied by other manufactur‐
ers.
• The use of radios supplied by other manufacturers may affect
the aerial amplifier. Genuine Audi radios have a “remotely
powered” aerial, i.e. the aerial amplifier receives its voltage
supply via the central core of the aerial cable. Use is therefore
to be made of remote power supply adapter from the Audi
range.
