Confirmed. This thing is awesome and great to have someone spell it out for my technically, mechanically, and, in-general, sometimes-mentally-challenged-self.

I'm still playing with it, but it's not changing the language for me? I haven't hooked up the relay either, as I'm planning on buying an X5 later as well. I don't think this should affect it though, as I am able to turn on the fence alarm. Maybe you can't change SMS language to English in China? Like I said, in-general, sometimes challenged.
