I'm the guy who had speaker problems with his 7... To make a story short everyone said one or more bad speakers and further trouble shooting....
Researched it and purchased a used Logic7 from http://www.bmrparts.com/index.htm Bavarian Auto Recycling, one of the largest, most experienced, and most organized BMW recycling facilities in the world -- (over 10,000 BMW's dismantled) Quote from there website... After that everything worked fine.
Replacing it took me about a half hour, It took longer to get everything out of my trunk. Hot swap. no programing and you'll be good to go...
