As described above, the vehicle-mounted electronic device system according to the present invention can be expected to have the following effects, as is apparent from the above-described embodiment. -Since the operation state of each electronic device unit can be displayed on the display surface of the display unit in a large scale using the display surface of the display unit, the display of each electronic device unit is easy to see. -By using unit trays, even different equipment units can be shared and stacked in the same chassis in a stepped manner, and the equipment units can be adjusted with respect to the unit tray. ,
By adjusting the position with respect to the unit tray, the position of the equipment unit with respect to the chassis can be easily adjusted. In other words, since a plurality of equipment units can be installed at predetermined positions in the same chassis, modularization of the system can be achieved, and a plurality of equipment units can be easily integrated into a vehicle in a unit of a module. Therefore, the cost can be reduced and the cost can be reduced. The system module can be easily changed by changing the position of the step in which the device unit is installed in the chassis or changing the type or combination of the device unit. -Since there is no need to provide a chassis or panel material for each device unit, it is possible to reduce the weight of the entire system and to simplify the structure.
