Bought a used 1996 S500 a few months back. In the glove box was the users manual (including the radio manual), but no code for the radio. Went to the local Mercedes dealer (an hour drive away!), gave them the VIN, registration, etc, and the service advisor looked up the radio code on his computer.
Today, I replaced the battery. After reconnecting the battery, the radio asked for the code.
I followed the instructions to the letter... put the key in the Number 1 position, turned on the radio, and entered the 5 digit number. Pushed "SC" to confirm the code ... and, it asked for the code again. After three tries, it displayed "WAIT", which according to the manual means the code I'm using is incorrect.
My guess is that the radio has been replaced sometime in the car's history (I don't have any service records) and the code the dealer gave me was the original.
Does anyone have the ability to look up the code by the serial number?
The radio says BECKER BE1692. Serial is T1053019.
If you can find the code for my radio, please send it to gearhead285@hotmail.com
