Navigation System, In-Vehicle Apparatus, and Portable Terminal

摘要

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 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 performed by an in-vehicle apparatus and the portable navigation device in cooperation with each other.
