Understand how to operate the wide screen monitor. Review the procedures to access the Service Modes. On-Board Monitor and Navigation Systems 15 Introduction While the instrument cluster provides all of the important vehicle status information to the driver, the on-board monitor is designed as an additional display that can be viewed by both the driver and vehicle passengers. Information relating to the vehicle, navigation, audio system and telephone can be displayed and controlled from a central location. The wide screen on-board monitor replaces both the 5.5 versions in the E38 and E39, and the 5 board monitor from the E53 and E46. The wide screen display has a screen size of 6.5 and an aspect ratio (length:height) of 16:9. The benefits of the wide screen design are: Larger display area and higher resolution (400X234 pixels). Improved display screen technology (Ad-TFT LC). Bigger text size. Soft keys replace country specific audio function keys. Used for all board monitor applications in all markets reducing variants. Larger display area makes split screen and magnification features possible (future software enhancements). 16 On-Board Monitor and Navigation Systems Component Overview The wide screen on-board monitor consists of: 1. Monitor housing with cassette drive 2. Display screen 3. On-board monitor control panel Cassette Drive The cassette drive is located behind the on-board monitor screen. In order to access the cassette, press the eject button, the display screen tilts forward to uncover the cassette slot. The images will remain displayed on the screen. After pressing the eject button again or automatically after 15 seconds the display returns to its normal position (cassette must be completely inside or removed). The tilt mechanism for the display screen utilizes anti-trap, if the board monitor detects a sudden change in speed, the display will reverse direction. On-Board Monitor and Navigation Systems 17 Display Screen and Control Panel The display screen has a diagonal width of 6.5 and an aspect ratio of 16:9 compared to the previous monitors that had a ratio of 4:3. The new screen also uses a Ad-TFT display (Advanced Thin Film Transistor). This type of screen uses ambient light in addition to backlighting in order to illuminate the display. The advantage is a constant contrast and brightness level at all ambient lighting conditions. 6.5 INCH DISPLAY 16:9 ASPECT RATIO INFO 1 2 3 FM MODE 4 5 6 AM On-board computer DSP Code Emergency Monitor off MENU GPS-Navigation Aux.
