(Significant!) Routing differences in F5+ vs Garmin Connect navigation

Former Member

Morning/afternoon/evening all,
I'm hoping someone might be able to explain this fairly easily, but i'm confused at the moment.
* Yesterday i wanted to run to a certain location on the other side of London. I thought it easier to create the route on GC, save it and export it to my F5+ so i was ready to go. I.e. let the computer do the heavy work and use the watch for live turn/navigation info.
* I tried using both the 'popularity routing' and 'follow roads' and both courses were fairly similar (popularity was 7.0mi, follow roads was 6.9mi).
* Both methods followed a fairly major cross-city road for most of the mileage and both were almost identical to the (presumably THE most direct) route on Garmin maps (7.0mi, interestingly)
* when i got back home and before going inside, just to compare, i tried using the F5+ to navigate from and to the same location, again with 'popularity routing' enabled... and it took a completely different route of over 9mi. Almost entirely off the major roads, and following small back streets pretty much all the way. A far nicer route (i think) but many (many) more turns, and c.1/3rd longer! Great if time/mileage were on your agenda, but awful if you just wanted to get somewhere quickly.
My questions:
* why the disparity? is popularity routing not working correctly on GC? it feels odd that they're so close to 'follow roads' on GC.
* ideally i'd be able to easily choose between long/scenic (F5+) and efficient/direct/Google-equivalent (GC) routing, actually on GC or on the F5+ itself...but given GPS is really only available outside, and outside GC is on the phone that isn't with you... so this feels tricky. Can i view the F5+ 'navigation results' on GC (indoors) ? And then select what route i'm taking rather than doing it while waiting for a GPS signal in the freezing cold outside, while trying to remember how different the route is from the GC course?
Many thanks for your thoughts.
John
  • If you have a look at the options for routing on the watch, on a per activity basis, you can choose what the algorithm prefers - minimise time, distance, elevation. My guess is that the data sets are different (GC will have the latest), and the algorithms might be different (because the watch and GC can operate with different resources).

    Ultimately I use the GC (app/website) routing to get me a course I'd like to follow, and use the dynamic routing of the watch for "oh" situations when out (IE, I'm lost mountain biking, and need routing in the dark back to the start).
  • Crutlefish, how do you create a route on the GC app that doesn't have the same start/end point? Mine only seems to create round-trip courses. Navigate-to on the watch is fine, just can't see a way on the phone - any idea, or is this a web and watch only feature?
  • After "Create a course" in the next screen set the "Drawing methode" to "Custom".
  • Thanks blavla , but as mentioned I don't see this on the GC app (android), only on Web.
    (...and sorry for hijacking this thread, should probably have started a new one :-)

    I have similar problem. I plan my trip in osm map and next send it to watch where I use pl topo map. But maps are different.
    Is there any way to recalculate the route on the watch?
