So I know there are a multiple posts about problems with the radio and it cutting in and out, blinking on and off, etc., but most of those that I've read also include problems with dash lights, power steering, stabilitrak, etc. On my '12 ECO 6M it is Just the radio, and fairly infrequent, once or twice every 3-4 days. When it happens, it blinks on and off rapidly and tries to reset, acting like it's a loose power cable or ground. Has anyone had this problem where it's just the radio? Could this be the negative battery cable? I'm inclined to say not since it's not affecting anything else. I have a dealer appt next week for oil change, but they want $120 just as a minimum charge to start looking for the problem. And they're telling me there are no TSBs that apply. I'm hoping there is just a ground wire that can be tightened or cleaned up - any thoughts??

Rob and others, thanks for the info. That is exactly what I needed. I have the letter from GM about the extended warranty on the batt cable - I will insist that the repair be performed at no charge. Really glad to hear that it can affect JUST the radio.

Quick follow up: the dealer (Alan Webb in Vancouver, WA) replaced the negative battery cable. Haven't had any problems since, but the problem I was having was pretty infrequent prior. Hoping it solved the problem permanently. I was a little worried when I took it in since the service rep said they would have to duplicate the symptoms there at the dealer. I was thinking there was no way they'd be able to, but I'm guessing there's a procedure for checking looseness at the terminal, resistance, or other tests that take the place of duplicating the symptoms. In any case, I now have the new one and hopefully all is well! Thanks for the assistance.

No problem, Rob. Hope it helps someone in the future.
