BMW is seriously committed to FOSS as an Infortainment platform in their cars - they are not the only ones. They have set up something called the GenIVI Alliance which is an automotive industry consortium which is working together on this type of software: http://genivi.org/ Many other companies have joined as well, like GM, Nokia, Navteq, Intel, Freescale, Nissan, Monta Vista, Pugeot, and Texas Instruments.
