Need Help on Entering Radio Code.
 

I have my code for my radio but I have no idea how to enter it. I already tried entering the code several times with no luck. Can someone please help me. I have a '91 190E 2.6.

From the Becker manual

The radio is theft- protected. If it is disconnected from the vehicle power supply or the power supply to the radio has been otherwise interrupted, “CODE” will appear on the display the next time it is switched on. After pressing the button, the prompt “CODE” is displayed, followed by 4 stars. The four- digit
code must then be entered using the multi- function buttons “1- 0”.

Example : Code number 1530 (the code number can be found on the enclosed CODE CARD).

Enter the code number using the multi- function buttons.
The first star is erased after entering the first digit. The second star is erased after entering the second digit, and so on. The radio automatically switches itself on if the code is correct after entering the fourth digit.

If an incorrect code is entered, the prompt “CODE” and the four stars are displayed again. If an incorrect code is entered three times in succession, the prompt “WAIT” is displayed and the radio is locked out for approximately 60 minutes. After three more subsequent incorrect entries, the radio is again locked out for approximately 60 minutes.
The lock out time will only count down if the radio switched on.


1530



If you have the alpine radio, use the number buttons to enter the code than press the * button (mode button) if you don't have the code, you can take your vin to the dealer and they should be able to get you the code (assuming your radio was the original that came in the car when it sold new.)
