Have an 02 CLK430 w/dealer installed cd changer and Motorola V60. When I start the car, it says no phone/no cd changer. Sometimes restarting will work, but usually it does not. Anyone had this problem and if so, what was the outcome. Would this kind of problem affect the battery? Car has 2000 miles on it and one day the battery was completely gone for no reason (nothing left on). Dealer has had the car for 2 weeks (not the first time they've tried to fix it). PLEASE, if anyone has had this problem, were they able to repair it and what was the problem. The service records on this car look like a book. Thanks.
