radio/lights stopped working

i installed a stereo into my 08 aveo about a month ago. It worked for about a day, then stopped. Along with the stereo not working, most of my interior dash lights, my passenger side tail light and head light and fog light, and my clock are all out. Also my tire pressure sensor flashes for about a minute when I start the car, and my shift is stuck in park unless I use the shift lock release. I tried replacing the fuse for the headlight, but it has done nothing. Both brights work, turn signals work, AC works, overhead lamp works. Any suggestions? Driving at night in darkness and silence is driving me crazy.
