You need HIGH not Professional.

People get confused as BMW refer to the Mk4 system as Navigation Professional (and the small orange screen in the radio version as Navigation Business).

The 2002-2 is the 2nd release of 2002. They usually do two a year. The latest at the moment is 2007-2 but there will no doubt be a 2008-1 released in the near future.

The DVD should say whether it is HIGH or Professional on it - is it a copy?
