I looked for similar posts in tech info, but didn't find anything that helped me. Drove yesterday, and everything was fine. This morning, no radio. Fuse looks fine. Everything else works. Any ideas?

did you check all the radio fuses in the car? even under the back seat? When I installed a deck into my GA I thought I had pulled the fuses for the radio but apparently I had missed one and finally found it when the radio wouldn't turn on.

Checked the box under the seat and under the hood. I only see an "Audio" fuse marked under the seat. It was a 10a fuse and was fine. Its the stock radio, by the way. Like I mentioned, it worked yesterday. It is acting exactly like I would expect if it were a fuse though. Is there a relay I should check also?

If the fuse is good, your next step would be to look at connector & wiring harness on radio to make sure all is securely connected. There are no relays for power switching. Power is switched on/off internal to the radio after VIN confirmation via serial link.

I got sick of trying to hunt this down and took it to the dealer. Thanks for all the input. They determined the radio is bad. Replacement is on order.

There'* another thing though. A while ago, I had the "Service Stability Syste" message pop up, then shortly after the ABS and Traction Control went out. I let it be over the winter. It turns out there were a couple of melted wires against the headers, and the (I forgot the precise name) module that controls these is fried, probably because of the short caused. So the lesson seems to be, pay attention to the message center. Who knows if I could have saved some money having it in sooner.

I agree, the message center, service engine soon and other warning lights serve a purpose. Ignoring them could not only be costly..but hazardous.
