4:3 Navi w/Tape deck with DICE issue

[canaryM]

Hello X5 gods,

I have an E46 with 4:3 Navi with tape deck. I installed the DICE unit via my CD changer cable but when I hit mode on my radio, I get "no tape" but it never changes to CD changer mode. Also, when I connect my iPod to the DICE unit, the iPod is not charging. The screen does come on when the dock cable is connected but I don't think power is needed to make that happen. Is my DICE unit bad? Any help is much appreciated. I searched around but of course I'm finding X5 related issues...haven't found much else. Thanks guys!
