I have a 2018 model RT LE.I have just purchased a 16 Pin GS 911 USB version.Unless you really do need the WiFi,the USB version,which does everything the WiFi does,is £100 cheaper.Either way if you own a BMW bike and intend to service it yourself,the GS 911,is the only way to go.The best deal I could find for the GS911,was from Gendan LTD,in Swansea.Hope this helps
