In these models the anti theft feature is built internally so if you were to swap the radio with one from another car it would not function for long before displaying this message. If you did not swap this from another car and its displaying this message then there can be an internal issue that requires either updating the software or replacing the radio. Either way the only place that can unlock the anti theft feature or update the radio is the dealer. This is not like older models where i can just supply you with a code . It is all done with a scan tool and linked online to merceded servers. If there were an easier way i surely would tell you. But you need to take this in to a dealer to get it unlocked. Hope this information helps Please take a second and rate me 5 stars in the top right corner of the chat if you feel I have been helpful and please request me in the future. Thanks for choosing just answer! Also , if you feel I deserve one , BONUSES are GREATLY APPRECIATED !
