I cannot knowledgably comment regarding the 210, but I bought my 203 prior to the comand availabilty. When I bought it, there was a factory rep in their facility who we asked about retrofitting at a later time. He contacted the factory and we were told that there were different GPS antennas and other issues involved that would make retrofit extremely difficult or impossible.
I would assume that this would apply to your car UNLESS the car was built after the date at which comand was available in the 210.
Best of luck,
