a transmission/reception unit connected to the controller and configured to receive a signal to request enabling wired or wireless data communication of the smart devices; and a display unit connected to the controller and configured to display priorities for the respective listed services according to control of the controller. ### Claim 2 (depends on 1) The system of claim 1, further including: an input unit connected to the controller and configured to input or select a predetermined command to determine the priorities of the respective listed services manually provided by a user of the vehicle, wherein, in a response that the user determines new priorities through the input unit, the controller determines a new integrated list and displays the new integrated list through the display unit. ### Claim 3 (depends on 1) The system of claim 1, wherein, in a response that the priorities for the respective services are listed, the controller is configured to list the priorities of the respective services while applying weights depending on a frequency of usage of each of the smart devices or a service for each of the smart devices. ### Claim 4 A method of providing an integrated projection service of a plurality of smart devices in a vehicle, the method including: making a request to a head unit of the vehicle for connection to enable wired or wireless data communication using Wi-Fi wireless communication technology provided in the vehicle, by at least a smart device positioned in the vehicle; and approving, by the head unit, connection of a smart device, searching, by the head unit, for service information to be provided by each smart device, and listing, by the head unit, retrieved services to be integrated. ### Claim 5 (depends on 4) The method of claim 4, further including: receiving, by the head unit, a user's manually adjusted priorities of lists for the respective services displayed on the head unit; determining, by the head unit, a new integrated list according to the user's manually-adjusted priorities; and displaying, by the head unit, the determined new integrated service list. ### Claim 6 (depends on 4) The method of claim 4, further including: displaying, by the head unit, a previously stored integrated service list on the head unit in searching for service information to be provided by each smart device, when there is a history in which a predetermined smart device has been connected using a same Wi-Fi network. ### Claim 7 (depends on 4) The method of claim 4, wherein, in a response that the priorities of the respective services are listed, the head unit is configured to list the priorities of the respective services while applying weights depending on a frequency of usage of at least one of each of the smart devices and a service for each of the smart devices. ### Claim 8 (depends on 4) The method of claim 4, wherein, in a response that another smart device is connected in a state in which a service of a predetermined smart device is being executed, the head unit is configured to compare service priorities of the predetermined smart device and a newly connected smart device, and provides a predetermined service according to one condition among a first condition in which the service priorities of the predetermined smart device and the newly connected smart device are a same, a second condition in which the service priorities of the predetermined smart device is higher than the service priorities of the newly connected smart device, and a third condition in which the service priorities of the predetermined smart device is lower than the service priorities of the newly connected smart device. ### Claim 9 (depends on 8) The method of claim 8, wherein in a response that the first condition is satisfied, the head unit is configured to maintain a current service thereof which is already connected and executed and, in a response that a service of the predetermined smart device is terminated, the head unit is configured to display a preset pop-up window on a display unit to allow a user to reset the priorities. ### Claim 10 (depends on 8) The method of claim 8, wherein in a response that the second condition is satisfied, the head unit is configured to maintain a current service thereof which is previously connected and executed. ### Claim 11 (depends on 8) The method of claim 8, wherein in a response that the third condition is satisfied, the head unit is configured to stop in a predetermined time period or terminate a current service thereof and to display a pop-up window on a display unit to ask a user to use another service of the newly connected smart device. ### Claim 12 (depends on 4) A non-transitory computer readable recording medium having recorded thereon a program for executing the method of claim 4.
