Abstract
A basic navigation operating part implements basic navigating function, such as current position and route computation. Meanwhile, an extended program for extended navigating operation, typically used to present multimedia information, is described in a general-purpose language such as Java. A virtual machine interprets and executes this extended program. If a navigation control code related to the basic navigating function is generated during the execution of the extended program, the service module,translates it into a format interpretable by the basic navigation operating part. Thus, several Java-compatible multimedia facilities can be linked with the basic navigating function. Navigation system platforms can execute a chain of basic and extended navigating operations without being provided with a platform-specific program for extended navigating operation.
