This is my first Saab, it's a 92 900 16v 3 door. I'm very excited about buying it. But I have found that the radio isn't working. It just says CoDE. I looked all over the car for something written down, but no luck. Someone told me that I have to contact the MFG to get it to work. Is this true? And if so does anyone have the #? Please HELP!!! I love my music. Thanks for any & all Replys.
