Radio Fix
I have to say, I brought mine in twice for poor reception.
The first time the Service Rep claimed they "couldn't duplicate problem". Had no desire to leave it so when I brought it back I showed them how the radio wouldn't pick up a single station in seek mode. Now mind you I am 35 miles from Manhattan so there are plenty of stations.
The fix was a new windshield. I was told that Chevy authorized the replacement and that all SSRs would be eligible for new windshields.
However, I was not able to get any bulletin number and no one else I've communicated with on this board has gotten an automatic replacement.
Sorry to shed more darkness (not light) on this subject.
To me, the reception was just UNacceptable.
BUT, mine was fixed under warranty.
