I have a question about noise in the upgraded CD player in my 2005 roadster. I've searched the archives and found a number of posts about clicking noises in CD players, but my noise isn't that. Instead, if I have a CD in the player but am not playing it (playing the radio instead, playing nothing at all), the CD player is constantly in "search mode". It sounds just like the noise one hears when accessing a CD in a computer, for example, but quieter. It only stops when I either play the CD or remove it. Is this normal for the upgraded CD player? It is driving (pardon the pun) my wife and I nuts!
