I installed my Dice Silverline for my X5 today, everything seems to be communicating between the ipod and the factory radio (I see text, I can use the factory controls to change between songs, etc) - but NO SOUND.

I do have DSP - but since I have both the 3 pin and 6 pin connectors at the back that plug into the Dice unit plug, I was under the assumption I didn't need the DSP converter box. And I really don't want to spend $75 on one if I don't need it.

Help....!
