Dear Opelop, Last January I created a thread requesting an unlock code for a radio I'd retrieved from a junk yard to replace the broken radio in my 1995 Mercedes E320. You gave me a code, which unlocked the radio successfully, but that radio was broken (no volume). Yesterday I got another radio from a different junk yard and need an unlock code for it. I attempted to go to your web site, but didn't understand the language. I'm more than happy to pay a reasonable fee, and I see that you help hundreds (maybe thousands) of people free of charge. My newest radio is a Becker Model B1692 Serno V1144384. If this radio doesn't work, I've got a 30 day warranty and can take it back. Of course if the problem is "no volume", I'll know that my problem is elsewhere. Thank you, Harry Kidd
