Newbie here. I searched the forums and didn't find my issue. My stock Symphony radio would not power up the other day. It was not in SAFE mode, just no power. That night I pulled the fuse (#37 -20 amp) and it looked fine. I reinserted the same fuse and then started the car and hit the radio power and it powered up in SAFE mode. I entered the radio code and it worked just fine. I turned the car off, took the key out and then turned the car on a few times and each time the radio powered on and off normally. I thought it was "fixed".

The next morning, I started the car and the radio has no power. Tonight, I again pulled the 20A fuse, insert it and entered the radio code. The radio worked again. A few hours later, I started the car and the radio will not power up again. Any ideas or suggestions would be appreciated. Is there another fuse or relay that could be the culprit? Nothing else electrical appears to be awry. Thanks for the help.

BTW - I can't blow the horn when the car is not running, the horn will sound when the car running. Is that normal? It might be connected to my radio issue

To close out the thread, the problem ultimately ended up being my AUDI factory GPS navigation box in the back. It was stuck in the ON position and the radio was shutting itself down, probably due to excess power draw. Once I disconnected the Audi GPS the problem was solved.
