Abstract

An audio system interface is provided, as well as a method of using same, in which a visual representation of the vehicle'"'"'s passenger cabin is displayed on the vehicle'"'"'s touch-screen. When a user'"'"'s touch registers on the visual representation of the passenger compartment, the system matches the touch with one of a plurality of pre-defined acoustic sweet spots within the passenger compartment, and then adjusts the left-right speaker balance controller and the front-rear speaker fade controller to the specific left-right speaker balance setting and the specific front-rear speaker fader setting defined by the selected acoustic sweet spot.

9. The audio system interface of claim 6, wherein each of said first plurality of user selectable discrete touch sensitive regions corresponding to said plurality of left-right speaker balance settings is selectable via a touch-and-drag motion on said touch sensitive balance slide controller, and wherein each of said second plurality of user selectable discrete touch sensitive regions corresponding to said plurality of front-rear speaker fader settings is selectable via a touch-and-drag motion on said touch sensitive fade slide controller.

10. The audio system interface of claim 1, wherein said visual representation of said vehicle passenger compartment is photorealistic.

11. A method of selecting audio balance, the method comprising the steps of:
