Hi,
For now, Compare route with only contains TomTom and HERE.
A very nice feature would be if you could compare the route you planned with the actual tracklog of it. It happens that you made a mistake in the route planning and you noticed it while driving it, then when you get home, you want to make the route public, but you have to correct the problems. The thing is you don't remember perfectly everything, so a compare would be most welcomed.
Best regards,
Vlad
