When I optioned my car, I made sure the AMG Drive Unit was checked off. I took that option over heated steering wheel, at that time it wasnt available to have both options. Thanks to the pandemic, my order was ceased. Fortunately, the dealer had one but it did not have the AMG Drive Unit. 16 months after, I was able to retrofit the AMG Drive Unit to my OEM steering wheel. Super thankful and now I feel my car is complete.
