I recently purchased 1995 S420. Wow what an automobile! It has a Kenwood aftermarket radio in it. I dont really care for it and purchased an Alpine 9856 head unit and Scosche VW01B adapter connector from Best Buy. This should work right? I have pulled the Kenwood and I have the original Becker BE 1492 radio and wanted to see if it works. I need the code for it, if someone can help. Thanks in advance for any help. Love the group!

Serial Number R1120956
or 1492L20R1120956*
