Comfort system for vehicle by using bluetooth and method of providing thereof

PURPOSE: A convenience system of a vehicle using bluetooth communication and a providing method thereof are provided to prevent start delay when using an AVN(Audio Video Navigation) device by reducing the waiting time to the completion of booting. CONSTITUTION: A convenience system of a vehicle using bluetooth communication includes an integrated control unit(300) which compares driver identification information received through bluetooth communication with registered one and controls the booting of an AVN device(600) and the door setting before the driver gets on the vehicle. When the information accords, the integrated control unit confirms the communication state with a bluetooth terminal(100). In case of an error in the communication, the integrated control unit sets the vehicle door locked and cuts off drive voltage supplied to the AVN device and a door driving unit(700).
