1993 mercedes-benz 190-E when i turn on the radio a hold message appears i have the code but don't know how to put the code in


Use the numbered buttons on the radio to enter the code, then change the station to activate it. On few of the old models, we have to pull the radio out, hook up a tool to the rear and play with the buttons and activate it.

Let me know, if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!
