I have a 2010 E91 "Business Navigation" which claims that the navigation data is installed on flash memory (the "Professional Navigation" has the HD instead). Has anyone played with this? How to access this flash navigation? I wonder if it could just be mounted and the new files copied over. There must be a way.
