no, it doesn't work. I tried it. It just boots up like normal still asking for the password. My wife had the unit in her old car but we took it out when we sold it. Now I'm trying to install it in my truck but she can't remember what she set as the password. It's extremely frustrating that they would make their customers pay for something like that. I understand using it as a deterrent to people trying to steal them, but If I have proof of purchase and everything they ask for then why is it necessary to charge me? Hopefully someone can come up with some way to figure this out soon.
