Question about 1998 Mercedes-Benz M-Class
Use the numbered buttons on the radio to enter the code,
then change the station to activate it.
(check your owners manual for more detailed instructions)
If the radio does not say CODE when you turn on the car - it has been permanently locked from multiple access attempts.
Switch on the radio, "CODE" will appear on the display. Using the buttons on the alpha-numeric keypad, enter the five digit code. Confirm by pressing the "OK" key.
If an incorrect code has been entered and confirmed, "CODE" will reappear on the display. The correct code must be entered once again. If an incorrect code is entered three times, "WAIT" will appear on the display and the radio will be locked out for about 10 minutes.
Are you sure you have the right code? if not, call Mercedes Factory Assistance (800)367-6372 and give them your VIN, they'll give you the right code.
If the radio has no response (no CODE or WAIT displayed) you can turn the key to run position, and leave it for 5 hours. If it does not reset - a trip to the dealer will be required to activate it again.
Thanks for using FixYa!!

ENTER RADIO CODE
When the radio is first turned-on, “code” will display. To enter the code, rotate the right-hand knob until the correct number displays in the prompted location, then push & release the right-hand knob to confirm. The prompt will move to the next position; repeat the process until the prompt is again at position #1, then push and hold the right-hand knob until the radio turns on.
