Just a little bit of an update, for people who have this same problem, apparently nobody around here knows so I will give an update.

I ordered and installed the Blitz DSP converter, it was on Amazon for about 60 bucks or so. After doing so, both the Ipod sound and Sirius sound came alive.

Its interesting as most sites say, even the dice manual says that the converter is not needed when you have both the 6 pin and 3 pin plugs. Well in this case they were wrong. I dont know if it was because my truck has a build date of 12/02 or what.

Overall im happy with the Dice, sound is as good as it can be for an ipod, controls are easy for both sirius and ipod. Steering wheel controls still work and Artist/Album/Title displays on the mid for both Ipod and Sirius. Total cost was about $200 with the converter, which is not bad considering a factory Sirius kit would have ran about $500. I will take some pics if anyone is interested.
