To all owners of Mercedes always remember to lock your car. A knowlegable thief can made off hundreds of $$ of parts in your car in less than 10 minutes. The CCU, wood, switches, and the instrument cluster can be removed in that short time. Of course if a professional thief wants your car, that's hard to prevent - they could just jump or tow your car away. That's why you see so many brand new cars disappeared even though they have the latest theft prevention devices.
