1. A method for outputting data in a vehicle, comprising the steps of:
- connecting to a data bus a plurality of processing devices of a corresponding plurality of driver-information devices;
storing graphics data on a storage device connected to the data bus;
causing a processing device of one of the driver-information devices to generate the data;
transmitting the data from the processing device on the data bus, an output unit being connected to the data bus;
causing the output unit to receive the data via the data bus;
transmitting the graphics data from the storage device to the data bus;
processing the data that is received by the output unit; and
causing the output unit to output the data that is processed.

Abstract
Proposed is a method for transmitting data in a vehicle, and a driver-information device, where an output unit is connected to processing devices by a data bus. This allows an output for all of the processing devices connected to the data bus to occur centrally in the output unit, whereby, on one hand, only one output unit is necessary for a plurality of processing devices, and on the other hand, processing devices of different manufacturers can be connected to one output unit, when a common data-bus protocol is present.
