J2095: A Proposed Recommended Practice for CDROM Bootup in Navigation Systems

This paper describes J2095, a proposed “Recommended Practice” now being developed by the CD-ROM Boot Task Group of the Society of Automotive Engineers' IVHS Division. J2095 would enable CD-ROMS containing map data and other geocoded data to be run in any manufacturer's navigation hardware.

Upon bootup, the hardware searches for its executable file among the multiple executables on the disk. Because publishers could make their products available for several vehicles, the accepted practice would have the salutary effect of opening cars up to a common base of data.

At the same time, J2095 permits each manufacturer to design its own unique user interface. Manufacturers will also retain control over which independently produced data and software, if any, they will allow to run in the vehicles they produce.
