The radio in our 2007 no longer has any sound. It's the up graded radio. Light are on but no sound.
Anyone had the same problem?

 

There is a software update for 2007s that could fix this condition. If the update doesn't fix it the radio replacement should.

 

Had the same thing with my 2007, no chimes either, so I pressed the fuses down and they finally came on.

I had an issue were I would loss the sound in my radio, but at the same time I would loss the door chime and turn signal chime. After turning the vehicle off and then restarting it - everything worked (for a while). My dealership replaced the radio two times and was about to do it a third. They said thats what thier GM Troubleshooting book said to do. I contacted GM Assistance myself and finally got the issue resolved. I would suggest taking it to your dealer and having them check the "Body Control Module" looked at. That is what they had to replace on mine - thus far no issues. TTFN

 

Today it was working. If it happens again I'll take it in
Thanks for the replies
