Ok- So I figured out how it fits in there, but look at this picture. It looks like something should go from this part the opening above the taillight cover. I already tried to fit my CD Changer back it it but it doesn't work. I looked at some other BMW (95-96 325i) and found that the way they attached the CD changer is through a mounted metal bracket that then fits to the bracket attached to the changer- sorry that was confusing I don't have a pix- Anyway, whats up with this??
