Procedure:
To find the security code.
  1. Press and hold presets 2 & 3 or 1 & 4 for about 10 seconds until the first 2 or 3 digits of the display code are displayed.
  2. Write the numbers down.
  3. Press the AM/FM button; write down the next 2 or 3 numbers.
  4. Find a web site where they sell the unlock codes (the cheapest I found was $9.95). You'll use the security code to get the unlock code.

  5. Write down the unlock code and keep the unlock code in a SAFE place. There should be 4 to 6 numbers in the code.

To Enter the Unlock Code

  1. With the ignition on, press the "Set" button
  2. Enter the code by using the "Tune" button.
  3. Enter the first 3 numbers. The left side of the Tune button sets the first number, the right side sets the last two numbers.
  4. Push the "FM" button
  5. Enter the last three numbers.
  6. Push the "FM" button
The radio should come on at that point.
