The radio in my 2001 Grand AM is showing the word ERROR, it will not work, what is wrong?

Question

The battery was disconnected overnight, when we reinstalled the battery the Moonsoon Radio had the word ERROR on it and now nothing works, we can't even turn the radio on, set the clock, use the CD Player, Cassette Player, NOTHING, can you help me?

Answer 1

Did you set the code to the stereo you will also need to check if the original owner wrote the code to unlock the stereo on the car's manual.  the only way to may it work is to unlock it with the code you put in it or the original owner otherwise its useless but you can always take it to a pontiac dealer to unlock for a fee but its always better to buy a better stereo when this happens.  It also happened to me but lukily the original owner of my tahoe had written it on the manual.  If you found the 4 digit code give a try just follow the instructions on the manual.
