Question: Intallation help?

I have the AVH-P5100DVD with XM radio and Ipod already connected. I love it. I just bought the CD-BT200 bluetooth device. Here is my problem. I installed it myself. There where no outlets left in the back of the head unit, so I plugged it into the Ibus input on the XM. Is this what I am suppose to do?
It turned on no problem. I was also able to connect to my phone, but the audio is messed up. The contact can hear me, but I can't hear them.
I have the Sprint Samsung Epic 4G. Also, I am hoping to stream Pandora from my phone to my stereo, is this possible?
Please help.
