ABSTRACT:
An in-vehicle multiple cursor system properly provides information necessary for a user in case that the number of wirelessly connected portable devices increases to thereby cause lack of a memory space for drawing. A cursor operation for requesting a drawing occurs in a portable device. An in-vehicle navigation system thereby makes a determination as to whether or not a segmental memory space assigned to the portable device in a memory space of a drawing memory device has at least a predetermined data volume. When the determination is affirmed, necessary drawing data are read out from a resource database and forwarded to a drawing memory device of the portable device to be developed therein. A screen window is then displayed in a display unit of the portable device based on the developed drawing data.
