2005 Nissan Murano Radio doesn't work!?

Hi, My 2005 Nissan Murano's radio is not working. The radio powers on but no sound comes out. It doesn't matter whether its the CD or Radio or Tape or the DVD. I am not sure what it is but if someone could help it would be greatly appreciated.
Just wanted to add its the Bose radio with a 6 CD in dash changer and the DVD is in the center console.

i recon you didn't get 3 year extended warranty.
this is a very uncommon problem , sounds like a recall that wasn't published...
if all parts are original then you should go to your dealership and complain !

Whenever you have an electrical problem, you ought to check the manual and find the fuse for it and see if it's blown or not. If it's not a fuse, it's probably going to cost real money to fix.
