Yes, it ruined part of my month long vacation in the Pyrenees two years ago where I had all these Wikilocs offroad tracks which I had the Zumo turn into Trips which in Zumo terms is the same as Routes. It doesn't follow the tracks where there are no roads on the map and calculates a route via roads. (not recalculate).Schussboelie wrote: ↑Wed May 30, 2018 7:22 amHave YOU actually tried this? In the field (and not at your desk in GPS simulation mode)? Because I have, on more than one occasion...
I was convinced like you that nav devices can do routing when there are no roads but once you understand how nav devices route it will click why it can not work.
Somewhere on the Adventure Rider forum in the Zumo 590 thread there's an ultra frustrated rant by me (2016) why the !@$@$@ Zumo 590 can't do what I thought and you think it can do. All the guys said was routing doesn't work that way. Just follow the visible track.
It is so simple. Forget off the road trails. If I give you track which I rode on a mountainbike riding over bicycle paths only. Those paths are on the map but there are no roads legal to motor vehicles will the Zumo or the TomTom or the Tripy make a route over that track? No way.
Whatever profile you choose on the Zumo is motor vehicle based, no matter if it is curvy, shortest or fastest and it will calculate a route via roads legal to motor vehicles. The Zumo does have an offroad profile which is a straight line from waypoint to waypoint. Great for desert crossings.
You confuse the visibility of the track in combination with routing which gives you a meaningless ETA as the reason it works. Just load a track on your Zumo which has some serious not on the map trails. Let's say 50,34 km. Then tell the Zumo to turn the Track into a Trip which is the same as a Zumo Route. You will be presented by a map that shows a route following the track exactly with a length of 50,34 km. It must work?
Then press the button GO. The Garmin starts calculating a Route ( NO not recalculate because you have that turned off haven't you!) based on whatever profile you have but no matter what ... Wauw, suddenly the route is 56,78 km?
It is not my intention at all to be right about this. I've said over and over I want to be wrong... I just would like to debunk the perception that nav devices can do routing based on tracks that follow trails that are not on the map. It seems so many TET riders are wasting all this time like I did getting this to work when it can't.
Instead of getting into a verbal fight about this I could come over to Belgium and we go ride together and see if we can solve this problem of perception. I'd love to go ride with you.
That would be the TET spirit way of solving this :-)
