I am adding an amp tomorrow and I just called the dealership to ask about the radio code and I was told that the radio would have to be pulled and MB would have to be called to obtain the code. They had noithing on file that had the code. This seems like alot of work to install an amp and a sub. I have serched and can't really find a definitive answer, though some say that the C coupe does not use a code and some say it does. Is there any "grace" period when disconnecting the battery? I mean if it is just un-hooked for a few minutes will everything still reset? I have an '02 C230 and any help will be appreciated.

 

1) Your stealer is full of it because all they would have to do is to run a VMI on your VIN and it lists it.
2) It shouldn't be necessary because you're hooked up through the fiber optics network.

i pulled my COMAND unit out this weekend to install my Satellite radio and didnt need the radio code. same thing when i put my audio10 in before i had COMAND.

 

Do you need a code for command? Is it ok to disconnect the battery without having to go through some type of reprogramming process?

 

Yes, you must go through a process if you disconnect the battery but surprisingly it has nothing to do with the radio. When you reconnect your battery the windows and sunroof will not autoclose and you will get a bap/esp warning on your dash display. The process is in your owners manual. You have to open/close your windows/sunroof and hold the button closed for a few seconds. Then turn you steering wheel lock to lock until the message dissapears, usually once does the trick.

On the cassette radio if you change something like add/remove a CD changer it will say PROD after 2 minutes of play, this will go away once you start driving the car, you may have to turn the radio off and back on a few times until it stops. Doesn't happen on the Audio 10 CD radio, only the cassette radio.

 

Well, all went well with the amp and sub install and the only issues was the auto-down windows. No radio code, no ESP reset, and no sun-roof reset. All is well and I have much better bass now.

 

i had to do that, thats a pain in the @$$. i had to first hand crank shut my pano roof, that was fully open. that sucked!

 

In case my battery ever needs to be disconnected, I called the MB dealer today to get my Radio Security code. The lady said they would have to remove the radio to get the serial #, to get the code. However, in my owner's manual, when referring to disconnecting the battery, it only says I would have to resynchronize the windows, sunroof, and ESP. It says nothing about the radio. So, I just want to double check: Would my radio ask for a code if the battery is ever disconnected? I have a 2003 c230 Sedan, no Comand, just Bose.

 

Last C230 to need a radio code was the 2000. None of the W203's use radio codes, doesn't matter if Comand, Bose or the standard radio.

 

when i got my command i took the old radio out and tested the comand but i didint have all the parts yet. when i put the radio back in it did the prod thing so i took the fuse out on the back of the radio for like a minute and it was fine.

 

Don't mean to talk off topic but how did you install a subwoofer?
