For those of you interested in the new Digital POWER SoundModule from MINI here's another official PDF explaining the accessory as well as providing further installation and techical information. There's a few bits of info that may be of some interest right off the bat. For instance it would seem that the DPSM is not available for those with the HK system. Further it looks as if the DPSM will only work with cars produced after 10/03.
You can download the entire PDF here.
Update: We now also have the official MINI install instructions for those interested in not only how it works but how it goes in. You can download the PDF here.
