Have connected my 2016 GS300h without any problems just after purchase. To be honest there is not much there except planning the route beforehand on your phone and sending to the car. Not sure if traffic, weather forecast, fuel prices etc. require login as well or just internet connection over BT, but it all works as well. About a week ago had a popup on the screen saying something about software update required together with some webpage. As I was focused on the traffic did not quite get it, only split second before it disappeared form the screen. Asked local Lexus Stockport but they know nothing about it. Have not seen it afterwards.
