radio won't turn on on 2007 Cadillac DTS

I have a 2007 Cadillac DTS and today the radio just stopped working. I have also noticed that the turn signals work but don't "click" anymore. There may be more things but this is just what I noticed on the way home

I have the same car with the same problem. I removed the 15 amp radio fuse in the fusebox under the rear seat. The fuse was not blowm so I put the same fuse back it in the fusebox. The radio now works and turn signal clicks. I think the fuse removal reset the radio's computer. Car has no other known problems. Hope the repair lasts. Try this and let me know. Wil
