just got my car back from the shop, and went home to install my new cd player. I didn't even test the old one before trying hte new one, so i don't know if it worked, but.... i connected the new one and ****ed up, accidentally left the battery connected, anyways, it didnt turn on. I freaked out, and disconnected everything again, disconnected battery, and tried to connect old one again (plug and play, since they are both pioneers) and nothing turns on either. I took out the fuse for "radio/clock" under the dash and it doens't look blown. What else could it be?
