CD ROM Navigation Computer
The navigation computer consists of a CD-ROM drive, the hardware for navigation computation and a gyro sensor. The navigation computer generates the appropriate visual display output to support navigation functionality. Additionally the computer will provide the HMI (Human Machine Interface) for the On Board Computer. This is communicated to the display unit via an RGB video link for the LCD display. The navigation computer also generates the audible navigation instructions (speaker level) that are transmitted through the front channels of the stereo system speakers. The GPS receiver is an integral part of the navigation computer.
