Good morning, your radio code comes up as 21115.Let me know if it works.Marty
Customer: replied 1 year ago.
I entered the code and it says "wait" in the window now...waited 10 mins and it still just says wait.
Customer: replied 1 year ago.
Hello? You still there?
Expert:  Marty replied 1 year ago.
Hi, did the radio say CODE before you entered the code?
Customer: replied 1 year ago.
yes
Expert:  Marty replied 1 year ago.
Ok, then the code on file may not be correct. Leave the key turned on to the first click and leave the radio turned on until WAIT changes back to CODE. Enter the code one more time and press OK if you get that option on the screen otherwise press one of the arrow buttons. If the code fails you will need to remove the radio and give me the serial number from the radio and I can look up the code.

I will have to try this at my lunch hour, I am at work right now.
Expert:  Marty replied 1 year ago.
Ok, I'll wait to hear from you.
Expert:  Marty replied 1 year ago.
Hi, it won't matter if it has a CD player or not. The code is associated with your VIN number in the Mercedes database. If the 21115 code did not work the radio in the car must not be the same radio that came with the car. The only way to get the code is to remove the radio and give me the serial number that is stamped into the chassis of the radio.

Ok, still working on that. We are not very "stereo removal" savy...waiting for a friend to help us with that.
Expert:  Marty replied 1 year ago.
It's real easy to remove the radio but you will need to purchase the radio removal keys. The keys just insert into the slots at the bottom of the radio to unlock then you just pull it out of the opening. Copy and paste the link below for the keys.

Hi Teresa, were there any numbers or letters before that number?

I will need the complete serial number. Did you see the picture I sent you?
Customer: replied 1 year ago.
Yes
Expert:  Marty replied 1 year ago.
Let me try running that number you gave me again.
Expert:  Marty replied 1 year ago.
Ok, I got the code. 41326.
Expert:  Marty replied 1 year ago.
The radio must say CODE on the display before you can enter the code. If the radio says WAIT you need to leave the key turned on to the first click and leave the radio turned on until WAIT changes back to CODE. After you enter the code you may need to press the < or > to activate the radio.Let me know if it works.Marty
Customer: replied 1 year ago.
Now it says wait again after entering the code.
Expert:  Marty replied 1 year ago.
Did she enter the 41326 code?
Customer: replied 1 year ago.
yes
Expert:  Marty replied 1 year ago.
Ok, I double checked the code with the serial number 98B110722 and it comes up as 41326. Have here leave the key on and the radio on until WAIT changes back to CODE then try the code again and press the seek button. The radio should work with that code.
Customer: replied 1 year ago.
We will try this once it goes back to code. Thank You. Please leave this dialog open for a day or 2.
Expert:  Marty replied 1 year ago.
Will do. Let me know how it goes.Marty
