Mercedes has been making some changes to the 2010 C-Class options and packages to make it a better value and respond to the demands of the market.

Originally, Mercedes had announced that COMAND with navigation (512) could be ordered without the Multimedia Package (320). Then, due to factory constraints, that was dropped at the end of April and all vehicles that had been ordered with COMAND with navigation (518) were changed to Multimedia Package (320).

Now, Mercedes is changing the Multimedia Package (320) to reduce the cost of the package. So, the new Multimedia Package (320) will include
Voice Control (396)
COMAND with Navigation (512)
iPod/MP3 Interface (518)
Media Interface Consumer Cables (049)

The harman kardon (810) 450 watt sound system was dropped from the package and is now available as a stand alone option. Ordering Multimedia Package (320) also requires that either the Premium 1 Package (P01) or Sirius Satellite Radio (536) are ordered on the vehicle.

So, there you go. If you have a 2010 C-Class on order you might want to check with your dealership and see how it is currently equipped and if there are any changes you need to make to have it turn out like you expected.
