OK, thanks for the reply, that's what I thought. According to the merchants site I bought it from, the only restrictions on the unit I chose to purchase was, "DOES NOT WORK ON WATERCOOLED 1200GS OR K1600 MODELS. PLEASE SEE WIFI VERSION." I don't mind spending $100 more for the wifi version but by all indications this one was advertised to work on my machine. I'll have to contact the dealer I purchased from, and hopefully I can just send this one back, pay a little more dough, and get a tool that works. Thanks again for you reply.
