That is unfortunately correct. Even the Navigation in the upcoming E90 won't have the MP3 capability.
Lack of MP3 feature in the year of 2005 is unacceptable, IMO, but those, who are following BMW's audio development over the years, won't be surprised. Remember how many years did it take BMW to integrate a CD Player behind the NAV ? or and MD Player, which was a waste of investment and probably have been ordered maybe 10 or 20 pieces in all these years ?
