Sunroof problem

Has anyone had any problems with the sunroof in a 2005 Magnum (Hemi)? Mine just suddenly stopped working. Looked throught the owners manual to see if it could be a fuse but no luck. I just had a ipod adapter installed and I'm wondering if the tech accidently knock a wire loose behind the dashboard. The manual does not describe what each relay is for and after speaking to my dealer (who said there is a sunroof relay in the fuse box). Can anyone point me to a website that might have such a diagram?

Many Thanks
