Basically my car has not been updates since it was new in '04. I want to uprgade to the lastest firmware and maps. If at any way possible I want to get rid of the nav screen and a custom opening (think they call it splash) screen would be awesome.
I found a download for the firmware.
BMW Navigation Files @ neiloakley.com
and I downloaded v32 but not sure if I just save it to a cd now and slide it in or what. I will prly just buy the maps on ebay for $15. I'm sure if they don't work they are free so.
