2006 Tiburon GT Radio problems
 

This is in reference to my brother's car. He is having some issues with his radio where there is no display but the radio has sounds coming out of it as if it works. About 5 minutes after he starts the car, the radio will turn off completely and stay off. I'm not really sure what to look at. The only thing I could think of to look at was the fuse but I wasn't expecting to see much. I'd appreciate any help! Thanks

*sorry for kind of a broad description of the issue. I'll try to go back and test the cd player and what not and try to get more info.

*Looks like this happened after he changed his battery.
