A vehicle and a method of managing a user setting menu (USM) enables the vehicle to add a new function after production of the vehicle so as to effectively manage the USM. The method includes: acquiring, by a conversion controller, first setting information about at least one existing function from a system controller through a first network using a first protocol; converting, by the conversion controller, the first setting information into second setting information using a second protocol; transmitting the converted second setting information to a head unit controller to manage the USM through a second network; transmitting third setting information about a one new function from a connectivity controller to the head unit controller through the second network, and updating, by the head unit controller, the USM based on the second and third setting information.
