2010 CTS-V 80k on it and the speakers play no sound nor do nav or turn signals. When you turn the key you hear static for a few seconds then dead silence.

Dealer traced and said no power coming from amp. Is this a common issue with these things?

I am super fresh to the CTS-V platform but not to the LS platform. Tried some searching but not finding much.

Currently just trying to fix it.

 

My electrical gremlins turned out to be body control module. No turn signals, headlamp control, etc.

 

Turned out it was a combination of blown fuses and turn signal switch!

 

Hey bud I have the same issue with my blinker & radio noise . Replaced amp. Nothing , which fuses were blown ? Under the hood or trunk

 

I can't remember which fuses specifically but they were ones in the trunk behind that cover panel.
