Patent ID: 7528330

Claim:
A system for controlling a multimedia device disposed in a vehicle, the system comprising: a front panel unit adapted for mounting proximate the dashboard of the vehicle, where the front panel unit comprises a display that provides visual indicia corresponding to user selectable functions of the multimedia device; a controller in electronic communication with the front panel unit, the controller comprising a frame, a supporting plate supported by the frame and that is configured to move linearly with respect to the frame between at least first and second operational positions, a rotary-push-button switch fixed for co-movement with the supporting plate, at least one push switch disposed proximate the rotary-push-button switch and fixed for co-movement with the supporting plate, a position detecting element disposed to detect the operating position of the supporting plate, and a light element positioned within the frame and assigned to cooperate with the position detecting element, the light element configured to emit lighting characteristics and vary the lighting characteristics in response to the operating position of the supporting plate, where manipulation of the rotary-push-button switch is associated with a first mode by the front panel unit when the position detecting element detects that the supporting plate is in the first operating position, and at least two guide pins projecting from the supporting plate; where manipulation of the rotary-push-button switch is associated with a second mode by the front panel unit when the position detecting element detects that the supporting plate is in the second operating position; and where the frame comprises at least two holes that receive the at least two guide pins and where the at least two holes restrict movement of the supporting plate.
