Dice duo trunk install, x3

[bruce-x3]

I tried to install the Dice MediaBridge in the console on my 2008 - X3
I went thru all the steps, found the correct wires, etc. but no sound from the iPod.
the NAV display shows the song that is playing, but no sound
I also pulled the radio and tried switching the cables, still no sound.
I'm ready to tear this out and give up

Was the CD stacker working before you installed the Media Bridge or wasn't there one installed? If it was and you've installed the Media Bridge using the connections from it there shouldn't be any reason why it doesn't work. When installing did you disconnect the battery?
