If it's the base (non premium) radio there are 2 fuses for it. In the IP fuse panel fuse #29 should be a 10a, hot all the time and provides power to terminal 8 a light green and purple wire at the radio connector. Fuse #20 should be a 7.5a, hot with the ignition on and provides power to terminal 6 a yellow and black wire at the radio connector. Terminal 7 (black wire) and 3 (black & light green wire) are both grounds at the radio connector. If you have that and the radio won't power up you have a bad radio.
