Claim 8:
9. A control device for a motor vehicle to control a data interchange between the control device and an external device and perform a plurality of vehicle functions, each of which is assigned at least one subservice provided for use by several of the plurality of vehicle functions, the control device comprising:
a processor and a memory, such that the processor:
receives a deactivation signal for a first vehicle function of the plurality of vehicle functions and deactivates the first vehicle function;
checks whether the at least one subservice assigned to the deactivated first vehicle function is assigned to a second vehicle function of the plurality of vehicle functions, the second vehicle function being currently activated;
deactivates the at least one subservice if the at least one subservice is not assigned to the second vehicle function; and
terminates the data interchange between the control device and the external device carried out by the at least one subservice;

wherein:
the data interchange between the control device and the external device is automatic regardless of whether the first vehicle function is currently activated or deactivated,
corresponding data collection and data transmission from the control device to the external device occurs as a result of the activated subservice, even if the first vehicle function is not currently activated,
a link between each of the plurality of vehicle functions and the at least one subservice is stored in the control device, and
the checking whether the at least one subservice assigned to the deactivated first vehicle function is assigned to the second vehicle function that is currently activated is based on the stored link.
