Communication systems
The most important components of the communication systems in the Golf and Bora include the radio units or the radio navigation systems, the telephone system, the aerial system, the loudspeaker systems, the telematics system, the CD changer/player and the digital sound system.
Some equipment is optional so not all systems are installed in every vehicle.
  Note
t  When faced with complaints, it is absolutely necessary to understand the functions and how to operate the communication systems.
t  Additional information → Operating manuals → No.147 → No.199 → No.236 and → No.235.
t  For repairs or fault finding → VAS 5051 or VAS 5052, Guided fault finding → Current flow diagrams, Electrical fault finding and Fitting locations.
t  If the vehicle battery is to be disconnected for a longer period (e.g. repairs over a longer period), then pull connector off telematics control unit on vehicles with telematics system. This will prevent the telematics system emergency battery being discharged.
