Audio problem with new DICE Silverline unit

[Clam_Alert]

First, let me say I've searched old threads high and low and have found a ton of useful info, but am still having the following problem:

2005 X3 w/Business CD
Never had a CD changer
Sirius satellite installed and working perfectly since 2006
Aux input installed and working perfectly since 2006
Just purchased a DICE Silverline kit for the X3
Connected the CDC connector to the sirius receiver in the trunk area
Connected the CD-SDARS labeled 6-pin connector to the DICE harness
Connected the proper 3-pin connector (not the phone connector) to the DICE harness
Battery was disconnected during install
iPod has appropriate updates
The 12-pin CD-SDARS labeled connector is connected to the head unit

When I connect my iPod everything seems to work fine except that i get no audio. I can control the iPod with the radio controls, it scrolls through my playlists etc. etc. I just can't hear a peep.

Anyone have any suggestions? Can I hook up the DICE unit to the 3-pin and 6-pin connectors in the trunk area used for Sirius at least to test if it works from there? Maybe I have a bad factory harness from the console to the trunk


Thanks.
