The invention relates to an electronic device (10) for providing predetermined functions for a user (1) of the device, with a man-machine interface of the device for allowing function-related inputs by the user and function-related outputs from the device, a processor-controlled computer device for processing the inputs of the user and generating the outputs from the device, and coupling means for the electrical and/or mechanical connection of the device to a device support (14) associated with the device. To achieve simpler operation and a wider scope of application for such a device, provision is made according to the invention for the device to have means of detection for detecting the presence of a connection of the device (10) to the device support (14), and for the processor-controlled computer device to effect a modification of the man-machine interface (12) in the presence of the connection. A particular advantage consists in the fact that the modification of the man-machine interface (12′) can be specifically adapted, taking into consideration the application environment concerned (e.g. in the motor vehicle, in the home, etc.), in that during this modification the “device support type” is detected and taken into consideration by the device (10).
