Stereo messed up

[DaveBMW]

Since I've gotten my X5 last weekend, the stereo has some issues. In addition to the CD changer missing (seller had one sent to me now), the speakers on the passenger side are not working. I checked the balance, and it was set in the middle. I moved it to the right only and nothing. I think I could hear a faint bass from subs.

So, I'm going to be hooking up the cd changer, the fuse is out for that too, so I will put that in. I know there are other head units out there and I am evaluating them, but I want to get this working first so I know it is all functional before adding anything new.

Any idea where to look for the right speakers issue? Is there a connector that I should check?

I love listening to the engine but some tunes would be nice.
