Troubleshooting my (non)audio system

I was listening to my iPod last night on the way home from work, and the sound went out. Interestingly enough, it seems stereo still works, etc, because the mode button lets me switch, am, fm, etc, and I see that confirmation on the screen, I can adjust the volume, and it shows it on the screen, and when I scan it stops on the radio stations that are local and have a signal. I just don't have audio.

Furthermore, the nav lady still talks, and I can use the bluetooth phone to talk through the car as I normally would.

If anyone had any suggestions, it would be helpful, even though it seems Priuschat may not be fully functional. When I get a chance, I'm going to try disconnecting the iPod2Car, just in case that's it, but I've had it there for 5 months without a problem.

 

It was the ipod2car, broken after 5 months...
