1 Installing the Main Unit
Installation angle
The unit should be installed within an angle of 25 degrees from horizontal. If this angle is exceeded, the monitor may not open up or retract properly.
Before installation
This unit is designed to be completely safe, but if not installed correctly, it can cause accidents. Be sure to verify the following points before installation. Install the main unit to the in-dash location, and the connection box under the navigator's seat, etc. · If the monitor in the opened position is close to a airconditioning outlet, the outlet should be closed. · Install the unit so that the monitor when opened up will not block access to the hazard switch or other important controls. · Do not install the unit (monitor) in locations which may be subject to excessively low or high temperatures. (Otherwise the unit may be deformed and the LCD may be damaged.) Exposure to direct sunlight can also lead to high temperatures and should be avoided. Selecting the installation location

If the installation dimensions shown at right are not observed, the monitor may not open up smoothly. If this happens, check the installation once more and modify the cluster panel where the dimension requirements are not met. For some car models, a separately available mounting kit may be required. (For details, please consult your dealer.)

Set the ignition key to OFF or remove it. Place the units in their intended mounting locations to check the cable length and monitor installation conditions.
· To allow for proper opening and closing of the monitor, there must be a clearance of at least 147 mm between the closest position of the shift lever and the mounting surface for the unit.
Shift lever At least 147 mm from mounting surface
· In some cases, the shift lever may touch the monitor when moved to a certain position. Make sure that there is no obstruction to driving operations. · When installing this unit together with other car audio equipment (single DIN slot size) in a stacked configuration, install the Media Center main unit on top.

Refer also to the documentation for all other components in the system.
Also see "Connecting Information" on page 12. · Components listed here except for supplied accessories are available separately. When connecting such components, be sure to also refer to their documentation. For specifications and other information on separately available components, contact your dealer. Prevention of accidents caused by short-circuits To prevent the risk of accidents caused by short-circuits, connect the power supply leads (red and yellow) only after all other wiring has been completed, and only with the ignition key in the OFF position. Otherwise, accidental short-circuiting can lead to electric shock and to serious damage. When a fuse has blown, check the wiring and locate the cause of the problem before replacing the fuse. When replacing the fuse, be sure to use only a fuse of the same rating (ampere rating). Using a different fuse or bridging the contacts with wire is highly dangerous and can lead to serious damage. Make sure to connect all of the following leads. Otherwise there is a risk of electric shock, damage to the equipment, or malfunction. · Connect light green lead to parking brake switch lead of car. · Connect yellow lead to battery power supply of car. · Connect red lead to accessory power supply of car. · Connect black lead to metal point on car chassis. * Do not to mix up the yellow and red leads, as this will cause the memory contents to be lost. Observe the following precautions. Otherwise there is a risk of electric shock, damage to the equipment, or malfunction. · Cover unused connectors with electrician's tape to prevent accidental contact. · Route FM/MW/LW aerial cable, bus cable, RCA interconnects, and power supply leads as far apart from each other as possible, to prevent noise interference. · Always grasp the connector and do not pull the cable when disconnecting the bus cable or other cables. Otherwise the cable may become detached. Notes on the control and power supply leads · The power aerial control lead (blue) supplies +12 V DC while you select the radio reception or while you activate the AF (Alternative Frequency), TA (Traffic announcement) function. · When your car has built-in FM/MW/LW aerial in the rear/side glass, connect the power aerial control lead (blue) or the accessory power input lead (red) to the power terminal of the existing aerial booster. For details, consult your dealer. · A power aerial without relay box cannot be used with this unit. Memory hold connection When the yellow power input lead is connected, power will always be supplied to the memory circuit even when the ignition key is turned off. Notes on speaker connection · Before connecting the speakers, turn the unit off. · Use speakers with an impedance of 4 to 8 ohms, and with adequate power handling capacities to avoid its damage. · Do not connect the speaker terminals to the car chassis, or connect the terminals of the right speaker with those of the left speaker. · Do not connect the earth lead of this unit to the negative () terminal of the speakers. · Do not attempt to connect the speakers in parallel. · Connect only passive speakers. Connecting active speakers (with built-in amplifiers) to the speaker terminals may damage the unit. · To avoid a malfunction, do not use the built-in speaker wires installed in your car if the unit shares a common negative () lead for the right and left speakers. · Do not connect the unit's speaker cords to each other.

Power connection diagram
Auxiliary power connector may vary depending on the car. Check your car's auxiliary power connector diagram to make sure the connections match correctly. There are three basic types (illustrated below). You may need to switch the positions of the red and yellow leads in the car stereo's power connecting cord. After matching the connections and switched power supply leads correctly, connect the unit to the car's power supply. If you have any questions and problems connecting your unit that are not converted in this manual, please consult the car dealer.
