On device routing

TREBORBILL
over 5 years ago

I like my Edge 830 but am finding issues with features like physio true up and the on device routing.

When following a route from a computer the Edge seems good.

However, the on device routing to a destination seems worse than my 810. eg an 11 mile direct route becomes a 29 mile loop, or the suggestion that I climb over a hedge and walk around a muddy field even when set for road riding.

What could I do to improve this or do I just have to hope Garmin brings out a software fix?

    I've noticed this as well and tried a whole bunch of options - switching popularity routing on and off, changing route type, changing avoidance options etc etc but none seem to make any difference.

    As you said, routing is completely bizarre sometimes taking you on unnecessary detours, going around parts of a straight path on perfectly good bike routes and frequently taking the longest path between 2 points for no apparent reason. I've used the 810 and 820 and don't remember this issue.

    Apparently Garmin tried to fix this in an earlier firmware. Whatever change was made to firmware didn't do the trick. All I can say is thank goodness I have dynamic watch and their new widget as I can easily create routes on the fly on my iPhone and transfer them to the 830 mid-activity.

    How is your GPS setup? GPS, GPS+GLONASS, GPS+Galileo? Try switching it.

    It's a combination of how Garmin restricts the use of certain OSM categorisations of roads by default in their maps for the selected routing mode ie Road Cycling, which cannot be changed with any of the available avoidance settings. It's a real problem in the UK & the rest of Europe.

    There's some discussion on it here in the 1030 forum

    I've ended up installing 3rd Party OSM maps on my 1030, which work great

    Can confirm this. When i really want to be shure to navigate e.g. a shortest course to a target destination (without Garmin map parameter changes taken into account that try to optimize for faster routes and less turns) i use OSM from e.g. https://opentopomap.org.

    Have you tried using alternative maps. The different map bases classify the some routes differently. The device uses this to determine your route, so Garmin maps sends me down a canal towpath, but OS maps do not. The reason OS maps do not do this as I updated the meta data of the route. Can't remember what I changed now, it was a while ago.. Anyway this could be the route (root) of your issue.

    It’s all of Garmin’s maps including online. Hopefully they’ll fix it at some point as it can make the routing really poor, and probably isn’t that hard a fix if it’s already been done by other people like openfietsmap using OSM. As Garmin maps are on a lot more devices now they’ll have to address it eventually.

    I've been using 3rd party OSM maps for years (openfietsmap lite) - routing is still weird on the 830 when it was fine on the 820 and 810.
