I heard in s650 you put the shifter in manual "M" and hold both paddles and it will be temporary neutral to rev. I didn't tried it coz i knew this info while am travelling...i will try it once am back
I have got this where you buy the base fit between centreal air-conditioning outlet and you can choose the holder either magsafe or magsafe with wirless charging
