Abstract: In an electronic device having a housing containing electronic components and a front part connected to the housing and having control elements, the connections between the electronic components and the control elements are made using a first transmitter and a second receiver on the front part respectively aligned with a second receiver and a second transmitter on the housing. This arrangement obviates the need for mechanical connections which are susceptible to faults between the housing and the front part.

Abstract: The invention relates to a navigation system for a land vehicle having a measurement arrangement for supplying position, direction and/or distance data, having a data source arrangement for supplying navigation data, having an input arrangement at least for inputting a destination point, having a control arrangement at least for determining a route, and having at least one display apparatus for outputting navigation instructions. After receiving data from an identification sensor, the control arrangement uses stored data to determine the driver who is operating the land vehicle and outputs navigation instructions, matched to the driver, in predetermined regions or on predetermined routes.

Abstract: The invention proposes an audio and/or navigation system for a motor vehicle with increased user convenience, particularly when the vehicle is used by more than one user. The audio and/or navigation system has a memory element (2) for storing user-related system parameters, and means (4) for identifying the user as well as means (5), which are connected to the memory element (2), for selecting and setting the stored user-related system parameters for the user as current system parameters.
