Stock radio won't turn off
Earlier today I went out to my car. I unlocked the car and open the door to hear the radio playing. Keys are still in my hand. I was a little confused, but I hit the power button and the radio shut off. I'm hoping it's not killing my battery. Any ideas what could cause the radio to stay on? Fuse, wiring, ...? Haven't messed with anything on the radio for a long time now. Only thing that happened recently was that I helped someone jump their car yesterday. Didn't notice the radio on when I got in the car this morning though.
