I have just completed installing my new mObridge bluetooth module. It was fairly straightforward. These pics don't show everything, but show what I had the most difficulty with, which was where to place the unit. In another thread by sonixcz I have replied to some of the technical questions he had with the install. http://www.benzworld.org/forums/audi...-mobridge.html These pics are here for those who don't want to drill down into another long thread.
