The settings for average speed on motorways, A roads etc makes a difference to which route it chooses, but it doesn't expliain why it would get the distance wrongI don't know what it is about SatNavs that makes them do this. They all use map data from two providers (NavTech and ... I forget the other one) so it must be something in the logic code which calculates the route. I've tried many Satnav and I've yet to find one which doews not do bizarre stuff at some point.
I guess I'd just be happy if the satnav in my civic (when it finally arrives) is no worse than what I've used so far.
Ah so it could be the settings. I think the defaults are 60mph motorway, 45mph rural roads and 25mph urban which might not make sense if for example there are a lot of dual carriagewaysIn my case the distance is not wrong for the route it is choosing. It's just not choosing the shortest route.
I could understand if any of my route was on back roads, but it isn't.
Instead of taking me via Woodstock - Broadway - Evesham it's taking me out via Cheltenham.
