Anybody considering buying from the above source may want to checkout Google and other BMW boards for "Richard Mastny" (the owner of Freischlatmodule.de and several other domains) .... Feedback on his products is less than stellar and many folks have sent him money without receiving any products or if they received them they didn't work or have been built very poorly. There is a reason why the working modules from reputable companies cost more than 29 Euro
A very good company is
Audiotechnik Dietz and their BMW Multimedia Interface
