Thus, whomever wrote the firmware owns the copyrights to it (unless they sold it outright to BMW).
The navigation operating system is produced by VDO for BMW. BMW has a license to redistribute it to both their dealers and to the retail channel. If you want to be 100% legit, you can either have your dealer perform the upgrade (which may or may not be done at no charge) or you can order part 01-59-0-141-891 from any BMW parts counter. That is the NAV OS update CD. Note that the part number does not change when a new version comes out, only the "Index" number does. So you may get an out-of-date disc.
