Navigation System

System Description (cont'd)

Audio Unit

The audio unit receives the audio driving instructions from the navigation unit and transmits the instructions through the

front speakers even when the audio system is in use.

Display Unit

The display unit uses liquid crystal display (LCD). The LCD is a 7-inch-diagonal, thin film transistor (TFT), stripe type with

280,800 picture elements. The color film and fluorescent light are laid out on the back of the liquid crystal film. The touch

sensor on the front of the LCD is an infrared type with 20 vertical and 9 horizontal infrared rays to produce 180 sensing

points. The display unit transmits the signal from each operation key and the touch switches to the navigation unit.

Infrared rays

Microphone (Mic)

Receives voice commands and transmits them to the navigation unit for interpretation.

Talk Button (Voice Control Switch)

Activates the voice control system in the navigation unit to accept voice commands.

Back Button (Voice Control Switch)

Returns the display to the previous screen.ProCarManuals.com
