brandon, you might have either an older version of the OS or a custom made version of the OS... the custom versions go past version 10.0 (which is 100, which is 00) in order to allow the upgrade process started - the nav computer will load only a different version OS than presently in the computer, and to avoid confusion, some developers called their versions 10.1, or 10.2 or whatnot... on the other hand, your could be really realy old version that is not even in the charts...

there are many threads around (some posts i posted) with a part number for the BMW Original CD disk that contains the upgrade firmware along with language packs... the disk is about $10 from a dealer, the problem is to locate a dealer that actually has a disk in their inventory...

i am too lazy to dig around for my own posts with the part number but you sure can find that...

Oh, and QS7 posted his reply not to teach you how to find something, but rather for the next fellow who is too shy to ask a question, to be able to track the steps to finding things - some posts are buried to deep in the archives and folks tend to read more recent posts, such as yours...

anyways, before overwriting your firmware (no way to recover it), check to see if it is customized in any way - i had a customized file that had russian voice files along with cyrillics that was not factory released (at the time)
