Whilst creating a route in Spain with seasonal closures ticked it takes say 6 hours but the exact same route will take 5 hours 10 minutes with seasonal closures unticked why? I can understand how it works in high alpine routes but Spain in the summer?
What am I missing?
The MRA is entirely dependent on the information provided by the mapmakers. HERE is a map that is also maintained by users of HERE via a special website of HERE. This information can be processed quickly or it needs some time.
But before i scare you of about HERE, which map did you used to create your route? HERE, TomTom or OpenStreet Map (OSM)?
Like @herman-veldhuizen said, if there is a closure and this is not marked up correctly, it can have some effect on your route.
But, did you used enough waypoints as well? If you put 2 waypoints miles apart from eachother and in the online routeplanner the route you created takes 6 hours but after loading it in your navigation system or MRA Next app, he route is suddenly 5 hrs and 10min. it might be also that there is some road you did not selected to go pass it but the app uses it as a part of the route. This might have an effect of the time as well
But please, provide us with a link to tat route so we can cehck it also.
