Ultimate Lockpick 3 & DICE Audio integration

Hi all,

I was wondering if anyone could recommend a good resource to help with a DICE Silverline install on a 2008 Prius Package #7 (I think - NAV, Multidisc CD, Bluetooth, etc.). I already installed the Coastal Tech Ultimate Lockpick 3 a while ago, and that works well. But I'm not sure how to put it together with the DICE audio box.

When I plug the DICE into the plug that comes from the Lockpick, since the Lockpick is already installed into the radio, and try to switch to MP3, the MP3 option doesn't come up. I do still have an DVD player option, the CD changer option, two FM radios, and an AM radio.

Any help would be greatly appreciated!
