Aftermarket Radio Back to Stock/ No Chimes
I've been through similar older threads that help but not totally explain my situation.
07 Cobalt came with a aftermarket radio without a faceplate. I had access to a stock radio that I only had to get a GM mechanic to unlock.
When the aftermarket radio was installed the chimes and warning sounds were heard.
After swapping to the stock radio we have lost the chimes and warnings.
Does that sound correct? Does anyone now why chimes are heard with th eaftermarket, but not the stock unit?
Any thoughts appreciated.
