Oh, it's definitely a Kenwood. And I was hoping not to hear what you just said, that people have commonly experience problems with their products. I've never heard anything of the sort, but that doesn't mean it isn't true. It's been operating fine for many months now.

So far the possibilities are that the fuse blew, that it needs to be reset for some unknown reason, or that somehow, the accessory wire came loose. The last is highly unlikely. But if any of these are the case, I'll probably be outside in the cold all day attempting to guess my security code.
