I just bought a 2003 Z4 with Nav this summer and still getting used to using the display. When I switch the Nav screen to the radio/CD/CD changer display, there is a big black empty box below the station/artist/song information. Is there any information that is supposed to be here normally? Or is that area just reserved for selecting/scanning stations and turing RDS on/off - that's all I can find out about that area in the manual. It seems weird to have that huge display area all blank most of the time.
