JMULTI DISPLAY

1. General

D A multi display has been provided on the center cluster panel as standard equipment. A 5.8–inch wide

LCD (Liquid Crystal Display) with a pressure–sensitive touch panel has been adopted to ensure the
ease of use.

D A GPS (Global Positioning System) voice navigation is offered as an option. Through the use of the

GPS and the map data in a DVD (Digital Versatile Disc), this navigation system analyzes the position
of the vehicle and indicates that position on the map that is displayed on the screen. Additionally, it
provides voice instructions to guide the driver through the route to reach the destination that has been
selected.

4. Construction and Operation

Center Cluster Integrated Panel ECU

The center cluster integrated panel ECU transmits the vehicle information to the multi display in order
for it to be displayed on display. In addition, the center cluster integrated panel ECU transmits the cluster
panel switch signals to the air conditioner and combination meter integrated ECU. Because vehicle in-
formation is transmitted by the ECUs that maintain communication on the BEAN (Body Electronics Area
Network), the center cluster integrated ECU converts this information into signals for AVC–LAN use
and sends it to the multi display.
