The number of things "optional" depend on which variant you get, but BT and TSA (QS) are optional for both the GT and R. So I had to option the heated grips, screen and backrest on my R that are standard on the GT. I also have the QS and BT, and everyone is right, the QS is the better spend if you only had to pick one. But while the BT module gets a lot of hate, if you set it up right it does exactly what is says on the tin. But many people have issues getting it sorted with their chosen equipment. I reviewed it way back when I got it all working: Ride Tech
