Reading it through it can seem complex, it is actually very easy and only takes 5 mins.
I agree that if you are only using existing points and don't care about the route then it is of limited value - I needed to use exactly the same route as the cyclists for 400 mls and that is a lot of points to enter into the car satnav by hand!
But if it helps someone, it is worth posting (perhaps Volvo will read it and realise what the capabilities of Sensus are
- but then again ...)
