I had to perform some maint which required me to disconnect the battery, and the radio is requesting a code to turn on. I get that this is an anti-theft device, but I bought this car used and have no idea what it would be. Any work around? System/car is completely stock. 2000 E320

 

this can be canceled. I called customer care and they were able to provide it based on the VIN. Hopefully this can help someone else also....
