When an operation mode (a latest cooperation mode) immediately before removal of a portable navigation device and an operation mode (a latest independence mode) immediately before re-mounting of the portable navigation device are the same, an MPU performs processing using processing data in the latest independence mode and takes over a route-guidance operation or a content-playback operation that was independently performed by the portable navigation device. On the other hand, when the latest cooperation mode and the latest independence mode are different from each other, the MPU performs processing using processing data in the latest cooperation mode and takes over a route-guidance operation or a content-playback operation that was performed by an in-vehicle apparatus and the portable navigation device in cooperation with each other.

An apparatus and method for restoring data is provided for easily restoring a file that is carelessly deleted from a hard disk. A microcomputeris constructed as follows. An original file and a file for restoration whose extension is different from that of the original file are stored in a HDD unit. When it is determined that the original file is not capable of being reproduced, the filename or the extension of the file for restoration may be renamed, thereby restoring the original file. Even when the original file is carelessly deleted or not capable of being reproduced due to its corruption, the original file can be automatically restored using the file for restoration.
