after replacing the battery radio doesn't work needs a security code

1 Answer


You can contact any Mercedes Benz dealership which can get you the code for your radio. Check the owners manual as perhaps the previous owner wrote it down by the radio operation section. Good luck. Cost about $20 for me a few years ago.
