This paper gives a short historical background of how the need for information has evolved and how the design is influenced by a variety of factors. The communication and information exchange networks are used as a common base when comparing instruments, Information Systems, of today, tomorrow and in the future. The European design considerations, with few gauges, and only important information shown when driving, is explained with design examples and block diagram of Truck Networks. Information sharing networks, are in Europe, considered to be one of the most important factors for integrated information system design. Not only in the normal working condition of the truck, but also for “In Truck Diagnostics”, “External Diagnose” and “Remote Diagnostics” of the vehicle systems. For Truck Companies with activities in a global market, the Global Instrument, with flexibility in design, for adaptation to different markets needs and requirements is discussed.
