Hi, I have the GS-911 WIFI model, although I hard wirer it. I have used two lap top computers. One is a windows 7, and one is a 10. I have uploaded using the GS 911 down loader. I did down load updates once. No matter witch Bike (I have a 2012 & 2013), or witch computer I use. I run the auto scan first. Then when I go to the place I add my new service date it's ghostlike. It tells me "NO RESPONSE FROM CONTROLLER", and won't let me update it. So I still show "SERVICE" in my interment cluster. Every other aspect of the 911 Interphase seems to work okay on ether of the Bikes, using ether of the computers. Best regards Aaron...
