There will be full iPod integration with COMAND but album art displayed on COMAND screen is doubtful. Info here: http://www.mbusa.com/main/container.jsp?features/iPod/index.jsp
iPod integration will first appear on the new M-Class to be launched this spring and retrofit kits to be installed by the dealer for select models will appear shortly after. It appears us R171 SLK owners probably won't get it until early summer... and you must have the COMAND unit in the car for a retrofit to be possible. Lastly, only iPods with the newer dock connectors will work (so mini's will also work). It's all on the FAQ from the link.
