SYSTEM AND METHOD OF OPERATING SYSTEM

A system includes a first in-vehicle apparatus that is mounted in a first vehicle and that has a suggestion model generated by machine-learning combinations of first inputs by first users of the first vehicle and first operations of the first vehicle in response to the first inputs, and a second in-vehicle apparatus that is mounted in a second vehicle of a different vehicle type from the first vehicle and that determines, using the suggestion model acquired from the first in-vehicle apparatus, a second operation of the second vehicle in response to a second input by a second user of the second vehicle.
