i have a 2000 monte carlo SS and i love it. a couple days ago i was putting in an after-market head unit in with a scosche interface to retain all the chimes. i had ithooked up and the interface fell and got unhooked. i pluged it back in and then i didnt get any power, so i put in the stock radio and it wouldnt turn on either but the buttons would light up. i checked my fuses and didnt see any blown. i have no idea whats up, lookin for help
