I'm about to take delivery of a 2010 X6 5.0 with all options including the premium Harman Kardon Logic 7 audio system upgrade. Has anyone on these forums had any experience with this system in the X6...or even the X5? I am a professional symphony musician and an audio, video, acoustical consultant. I have researched the system that is installed in the X6 and X5 vehicles, and have complete knowledge of the design. However, it would be helpful to obtain some emperical knowledge from users in the field. With many thanks in advance.
