Well, I went down to my Mercedes Benz dealer to buy a part for my Mercedes. I thought, while I'm here, I'll see if I can run down a copy of this disc. So, I pulled out my droid, and pulled up the website and this thread, and got the disc number. They weren't able to sell me a disc, because they didn't have any that didn't come with a car. Apparently, it's packaged in the car with the owner's manual. However, after asking around, they gave me a number for Mercedes service, and I called the number and explained what I was trying to do. I told the lady, who was very nice to me, about the Quadraphonic Quad website, and she pulled it up on her computer as we talked. She even asked directions to the thread about the disc and I told her. I also told her that most of the folks on this website would love a chance to buy the disc if it involves a lower price and doesn't come with a car. I billed it as a money making opportunity for Mercedes. She said she would check around and call me back. So far I haven't heard back, but this occurred just yesterday. Cross your fingers quaddie folks, and hope that this effort does bear fruit. If it doesn't, maybe an Email to Stuttgart would accomplish the mission.
