Abstract
In a vehicle navigation system having a navigation program, an information browser program is installed to browse generally available information. The navigation program and the browser program share a part of a plurality of image data storage areas of a RAM which are normally used to store map images in executing the navigation program. The navigation program and the browser program also share character font data and a key input processing program stored in a ROM. Thus, the number of ROMs and RAMs additionally required to perform both navigation function and browser function can be minimized.
