RECODING Radio

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2001 Mercedes-Benz ML55, 2001 Mercedes-Benz ML430, 2001 Mercedes-Benz ML320, 2000 Mercedes-Benz ML55, and 2000 Mercedes-Benz ML430. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Before disconnecting battery, obtain 5-digit radio security code from vehicle owner. Radio will be disabled until properly recoded.
NOTE: Radio will not operate if power supply to radio is interrupted. Obtain 5-digit radio security code from vehicle owner before disconnecting battery.
  1. Turn ignition on. Ensure CODE is displayed on radio display. Enter code numbers using radio station buttons. For example, use station button No. 1 for code No. 1 and so on.
  2. After first number is entered, CODE disappears and number entered is displayed followed by 4 dashes. After entering 5-digits, confirm correct security code has been entered. If incorrect code has been entered, entire code must be reentered.
  3. Confirm entry of correct security code using "<" (less than) or ">" (more than) buttons. If an incorrect code is entered, CODE will be displayed on radio display. If security code is entered incorrectly 3 times, WAIT will be displayed and radio will be disabled for about 10 minutes.
  4. If, after 3 more attempts, correct security code has not been entered, radio will be disabled for 60 minutes. Radio disable time runs down only when radio is turned off.
