1. An in-vehicle apparatus comprising:
- a plurality of slots for connecting a plurality of modules, each having a connector for connection, to expand capabilities of said in-vehicle apparatus;
a control unit for identifying the kind of each of said plurality of modules connected to said plurality of slots;
a management unit for detecting insertion of one of said plurality of modules into one of said plurality of slots and for acquiring a module ID from the inserted module; and
an ejection detection unit for detecting an instruction for ejecting the inserted module,wherein the control unit determines based on the module ID whether the inserted module is a supported module or not, and registers the inserted module with the management unit when it is determined that the inserted module is a supported module, the control unit executes an activation sequence according to the kind of the inserted module, and when the ejection detection unit has detected the module ejection instruction, the control unit executes a termination sequence for the inserted module to be ejected.

5. An in-vehicle apparatus comprising:
-
a plurality of slots for connecting a plurality of modules, each having a connector for connection, to expand capabilities of the in-vehicle apparatus; and a control unit for identifying the kind of each of the plurality of modules connected to the plurality of slots, wherein said plurality of slots include a first slot for connecting a first module having a first connector for connection to add a first function, and a second slot for connecting a second module having a second connector for connection to add a second function, and said control unit identifies the kind of each of said first and second modules connected to said first and second slots, respectively, wherein the first slot is a slot for connecting a module, having a connector for connection and having a first impedance characteristic, to expand capabilities of the in-vehicle apparatus, the second slot is a slot for connecting a module, having a connector for connection and having a second impedance characteristic different from the first impedance characteristic, to expand capabilities of the in-vehicle apparatus, and the control unit identifies the impedance characteristics of the modules connected to the first and second slots, respectively. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)
