Abstract: A system for generating map data acquires, from a map database, map data to include a route from a departure place to a destination specified by a user. The system acquires, from a POI database, information to suit a purpose or taste of the user. The system generates specified map data, in which the information to suit the purpose or taste of the user is added over a map including the route specified by the user.

Abstract: An information retrieval device having an insertion slot for inserting a medium having data to be retrieved includes an input unit for sending a signal upon accepting an input, an eject unit for ejecting the medium in the insertion slot and a control unit for controlling the eject unit upon receiving the signal from the input unit after an ejection instruction is accepted by the input unit. The signal to the control unit from the input unit after the ejection instruction on the input unit establishes an ejection prohibition control with the eject unit for prohibiting media ejection operation of the eject unit while an ejection prohibition state of the eject unit is brought into effect by using the input unit.

Abstract: A semiconductor integrated circuit device has a pair of oscillator terminals that is respectively provided with two oscillation signals having phases opposite to each other. An oscillator circuit provides an internal circuit with a system clock signal based on the oscillation signals. A mode detection circuit detects that the pair of oscillator terminals is respectively provided with two input signals having the same phase, and provides a test circuit with a detection signal. The test circuit sets a test mode according to the detection signal, and provides the internal circuit with a predetermined test signal. By setting the test mode using a pair of external terminals, an increase in the number of external terminals of the semiconductor integrated circuit device can be prevented.

Abstract: A vehicle is provided with a navigation system that includes a traffic information receiver and a radio receiver. The traffic information receiver receives traffic information from one of multiple traffic information broadcasting stations having respective service regions. The radio receiver selectively receives (i) traffic information from one of the multiple traffic information broadcasting stations and (ii) a radio program from a radio broadcasting station. When the vehicle approaches a border between (i) a current service region where the traffic information receiver is receiving traffic information and (ii) a neighboring service region, whether the radio receiver is in use or not is determined. Based on the determination, the traffic information receiver or the radio receiver is tuned to a traffic information broadcasting station covering the neighboring service region.

Abstract: A route is set by reading map data of an area used for calculating the route. When this area includes a road pricing area, it is determined if there exists a road pricing area into where the user is permitted to enter based on the permission data (road pricing area to where the entrance is permitted and the permission period) read out from an IC card inserted in an ERP car-mounted unit and stored in a storage unit. When there exists a road pricing area to where the entrance is permitted, the road pricing area is excluded from the areas to be avoided, and the route is calculated.

Abstract: A navigation apparatus is connected through a LAN to a master ECU which outputs a vehicle ID signal including type information showing a type of a vehicle, and obtains the type information from the master ECU. The navigation apparatus stores a map describing specifications such as functions assigned to the steering switches which are sorted by the vehicle type, and sets an operating condition according to the specification corresponding to the obtained type information. For this reason, the navigation apparatus does not need modifying in mounting on the vehicles of plural types.

Abstract: In a navigation device, when a hardware switch is turned “ON” so that Valet mode is “ON,” use of destination designating methods using a memory point and a position of home is prohibited. When the hardware switch is turned “OFF,” a user authentication of a password input is required. When the user authentication is successfully executed, the use of the destination designating methods using the memory point and the point of home become operative. This enables an authorized user to use the destination designating methods using the memory point and the point of home, methods which relate to personal information. By contrast, this prevents an authorized person who does not know the password from accessing the personal information since the authentication is not provided. The leak of the personal information that is registered in the navigation device can be thereby restrained.

Abstract: An in-vehicle accessory system for an audio and navigation system includes a control device, a display, a TV tuner, a DVD player, a VCR, a GPS receiver and a switching circuit. The control device includes a ROM. The control device determines a region in which a vehicle is located based on a signal from the GPS receiver. Then, the control device determines whether outputting video signals to the display is permitted in the region based on information stored in the ROM. If the video display is prohibited in the region, the control device turns off the switching circuit to disable the video signal output from the TV tuner, DVD player or VCR.
