I just purchased a used Elantra for my daughter to gget back and forth to school. At the time of purchase the original owner had told me that the radio knob was broken and the radio would not turn on. However I have discovered that the radio is fine it just displays CODE when turned on. I have opened the dash (wwith some difficulty) got the serial number from the radio, and called both Hyundai USA, and three local dealers all without success. They either do not have the code or want a fee for providing the code. After reading some previous posts I have held the #4 button in while turning on the radio and the diaplsy becomes a 3X3 grid that looks like:
0 - 0- - -
- - 0
where the 0's are blank and the '-' are lines.
Can any one help me before I pull out all my hair?
Thanks.
