NAVIGATION SYSTEM / MULTI INFORMATION SYSTEM

FUNCTION OF MAIN COMPONENTS

Component		Function
Radio and Display Receiver Assembly		Receives operation signals from the panel switches and display panel, which allows flick or drag operation, and data from various components positioned in different parts of the vehicle and sends them to the navigation ECU. Processes navigation information and the operation status from the navigation ECU and displays them on the multi-display. Receives audio signals such as voice guidance from the navigation ECU and sends them to the stereo component amplifier assembly.
Major Components of Radio and Display Receiver Assembly	Multi-display Panel	Displays a map screen or an operation screen based on image signals from the navigation ECU. Sends operation signals input via the display panel to the navigation ECU.
Navigation ECU		Houses a navigation computer, gyro sensor and GPS receiver, and processes operation signals or vehicle status signals from the radio and display receiver assembly, controlling the navigation system. Sends image and audio signals, such as navigation information, and the operation status to the radio and display receiver assembly.
Major Components of Navigation ECU	Navigation Computer	Corrects the vehicle position based on location information calculated from GPS information, vehicle speed signals, information from the built-in sensors and the shift status. Applies the mark of the calculated vehicle position to the map data and sends the information and operation status to the radio and display receiver assembly. Sends audio signals such as voice guidance provided in accordance with the vehicle position, to the radio and display receiver assembly.
	Gyro Sensor	Detects the vehicle's vertical axis rotation speed (yaw rate and rotation movement) and sends it to the navigation computer.
	GPS Receiver	Demodulates GPS information received by the navigation antenna assembly, calculates the vehicle position and sends the position signal to the navigation computer.
Navigation Antenna Assembly		Receives GPS signals from satellites in orbit around the Earth, at an altitude of approximately 20200 km (12600 miles), and sends them to the navigation ECU.
Parking Brake Switch Assembly		Sends the parking brake position signal to the radio and display receiver assembly.
Instrument panel Junction Block Assembly BACK UP LP Relay		Sends an R shift position signal to the navigation ECU.
Window Glass Antenna FM FM-sub AM DAB-1		Receives radio broadcasting signals (AM/FM/FM-Sub/DAB-1).
No. 1 Amplifier Antenna Assembly		Amplifies radio broadcasting signals from the radio antenna and sends them to the radio and display receiver assembly.
No. 2 Amplifier Antenna Assembly
Steering Pad Switch Assembly		Sends operation signals from switches such as the volume switch, mode switch and voice switch to the spiral cable with sensor sub-assembly.
Spiral Cable with Sensor Sub-assembly		Sends operation signals from the steering pad switch assembly to the radio and display receiver assembly.
Map Light Assembly		Houses the telephone microphone assembly.
Telephone Microphone Assembly		Recognizes speech during voice recognition system operation and sends the audio signal to the radio and display receiver assembly.
Stereo Jack Adapter Assembly		Sends audio, video, or image signals to the radio and display receiver assembly when an auxiliary device is connected. Communicates with the radio and display receiver assembly via a USB communication line when a USB memory device, portable audio player (USB type) or Apple product is connected.
Combination Meter Assembly		Sends vehicle speed signals to the radio and display receiver assembly and stereo component amplifier. Displays navigation information, such as directions and route guidance, sent from the radio and display receiver assembly on the multi-information display.
Stereo Component Amplifier Assembly		Amplifies audio signals sent from the radio and display receiver assembly and sends them to the speakers.

FUNCTION

Navigation Screen

The navigation computer calculates the present position and direction of travel, then determines a route and calculates the driving distance based on the following information sources:

- Map data in the navigation ECU

- Global Positioning System (GPS) satellites

- Built-in gyro sensor

- Vehicle speed signal

- Reverse signal

- Parking brake signal

- Radio Data System Traffic Message Channel (RDS-TMC) signal
