2012 C350C Speaker Rattle
Even though my car is CPO, I'm afraid that the service department will say nothing is wrong with the speakers, and to that end, will be charged for the labor used to diagnose the problem. I'd appreciate any advice. Thanks.
Also, on a an unrelated note, does anyone notice that sound quality using bluetooth is not par with using the iPod integration system? Could it be because I have an older generation iphone (6s)?
