I just bought a 1992 Honda Prelude and the battery was unhooked the radio says code on it does anyone no the code to unlock the radio and directions for using the code.

Some manufacturers put the unlock code on the sticker in the glove compartment. You can take it to the dealership and let them unlock, but that will cost you. You will probably need the serial numbers off the player, and they may not disclose the information over the phone. Good Luck! There are sites on the web that sell a decoding device, I guess it just depends which ends up being cheaper.
