Yes and I think the hare should have beat the tortoise too if I'm remembering the fable correctly...
The stock head unit in a Crossfire is a CD only version of the Becker Monza. It does not have the hardware internally to operate a CD changer nor Aux-in. Once I find the post I will link to it but another Crossfire owner even called Becker and was told the same thing. Heck it even has the fiber optic port in the back of it but that doesn't mean it will work if you plug it in. Hmm maybe I'll install my old head unit in my wife's SLK230!
