Remove cover under steering wheel/fuse panel. Shine flashlight behind instrument panel towards the rear portion of the radio. There should be a sticker on a cream colored box with the 5-digit code. Might have to try looking in at different angles, but it should be in there. Different models, the box color is black, but there is still a sticker behind the radio.
