摘要 |
The navigation system comprises a data processing device 12, a bearing system 14, such as a global positioning system, a mass memory 16 (eg CD-ROM), and a reception device 18. The reception device 18 communicates with a remote first service centre 22 and with a remote second service centre 26; the second service centre may be a sub-unit of the first service centre 22. Visual and audible output devices 28, 30 are included. A route to a destination may be determined and the location of the vehicle on a digital road map is determined and navigation instructions are audibly and/or visually outputted to the driver of the vehicle. The most favourable route is made available to the vehicle as a function of an instantaneous position of the vehicle and of a specifiable destination point broken down into defined segments and detailed items of route information are provided off-board by at least one second service centre 26. |
