No, I haven't used the auto update. I guess to use it, I'd have to use a higher version number and have the file uploaded in the appropriate folder on your site. Since it's still beta. I don't think I would attempt it right now.
Since S&T can now start the GPS itself, and turn off-on the autoreroute, I'm thinking od doing away with most the general, start and navigate options sections. These sections are giving me difficulties in running Keys since MS modified the Start/Stop GPS button in 2009. Maybe I'll find a way to do it, but it will take time.
I still have 18 days left in the trial version and Vista to get it done. After this I can have another 60 days on another laptop, but using XP. A problem, I just had a substantial accident with my van last week. Nobody was seriously hurt, but the van repairs far exceed the value and I have to find a replacement for it. This will take more time too, then Xmas will come around. For the curious, no, I wasn't using S&T when I had the accident.
