Patent ID: 8214150

Claim:
An in-vehicle apparatus installed in a vehicle, a portable terminal being removably mounted in the in-vehicle apparatus, wherein when the portable terminal is mounted in the in-vehicle apparatus, the in-vehicle apparatus selectively performs processing in a route-guidance operation mode and processing in a content-playback operation mode in cooperation with the portable terminal, the in-vehicle apparatus comprising: first storing means for storing a first operation mode before the portable terminal is removed from the in-vehicle apparatus or is disconnected from a power supply and processing data in the first operation mode, the in-vehicle apparatus and the portable terminal performing processing in cooperation with each other in the first operation mode; first reading means for reading the first operation mode stored in the first storing means when the portable terminal is re-mounted in the in-vehicle apparatus after being removed therefrom or is re-connected to the power supply after being disconnected therefrom, and for reading a second operation mode existing before the portable terminal is re-mounted in the in-vehicle apparatus after being removed therefrom or is re-connected to the power supply after being disconnected therefrom, the second operation mode being stored in the portable terminal and the portable terminal independently performing processing in the second operation mode; same/different-mode determining means for determining whether or not the first operation mode and the second operation mode read by the first reading means are the same; second reading means for reading processing data in the second operation mode existing before the portable terminal is re-mounted in the in-vehicle apparatus after being removed therefrom or is re-connected to the power supply after being disconnected therefrom when the same/different-mode determining means determines that the first operation mode and the second operation mode are the same, and for reading the processing data in the first operation mode when the same/different-mode determining means determines that the first operation mode and the second operation mode are different from each other, the processing data in the second operation mode being stored in the portable terminal and the processing data in the first operation mode being stored in the first storing means; and processing means for performing processing using the processing data read by the second reading means, in cooperation with the portable terminal.
