I had the same problem - the tech from dice had me reverse the position of the dip switches and reinitialize. When that didn't change operation of the unit I switched them back - the Dice unit began working as it should, with text on the displays. I assume that perhaps the switches weren't fully seated in the on position.

I also noted that once it started working the ipod controls were locked out and the steering wheel and radio controls worked as expected. The Ipod screen will show a dice logo.

Hope this helps.
