Forget the voice controls on the phone ... yes it works but not very well ... depends on your accent ... don't bother with it
As for the headlight wash ... depends on what speed you're doing ... also good for p!ss!ng someone off who wouldn't let you pass on the motorway after they let you go by ... give them a long blast on the washer and watch them pull back lol
and the gearbox ... just take your time ... a bit of double de-clutching will help
