Minimise distance routing not working

Hi, when I ask the Garmin to make a route on the fly it chooses an incredibly long way around. I’m currently trying to use it to navigate across the globe so it would be very helpful if it didn’t keep trying to make me do 200km instead of 50km! I have the routing set at minimise distance.

  • Two problems.
    1. 1040 began to understand topographic maps, weights and coefficients of roads and routes differently. He tries more to build a route along the roads, and does not cut through the forest (than 830), on the same maps. On the same route settings (road/gravel/mtb/etc). I couldn't achieve the same route as the 830 on any setting.



    2. On various third-party topographic maps, I have identified several places through which 1040 cannot build a route. Building a route hangs or gives an error. 830 always builds well and without problems. In the photo, I indicated with a green arrow the place to which the route was built, and with a red arrow where I would like to build it again (+100 meters along the road). When you try to build a route, the calculation freezes. These points can affect the construction of long routes, because of which it will not be short, as before.



    So, I have described two problems that I noticed, resulting in a route that is not the sho

  • * So, I have described two problems that I noticed, resulting in a route that is not the shortest. These problems depend on the topographic map used, on some they may appear, on some they don’t (I use third-party topographic maps - they are localized, accurate, up-to-date, unlike the built-in ones from Garmin; maps, including those from the site garmin.ru ). I just wanted to say that in the new 1040, the route building is very different from the 830 and is not as efficient.

  • Note that the devices (all of them) can have issues if there is more than one map enabled for the same region. That is, multiple enabled maps that overlap are a problem.

    Some of these could be issues with map data but that can’t be checked without links to the locations (the screen shots aren’t enough).


    It doesn’t seem other people are reporting these issues.

  • Only one map was chosen for the region in all tests. There have been repeated reports about resetting the device when navigating.

  • There have been repeated reports about resetting the device when navigating.

    ??? You aren't taking about "resetting the device"? Who else is complaining about roundabout routing?

  • For example, the author of the topic complained that the route is not built as short as possible. Perhaps not everyone noticed this if they did not use previous models (which could build short direct routes). I noticed that on all my old maps (ToPo v3 2019/2020/2021 - 3 versions) the route is no longer built short. And on new maps (ToPo v6.39, OSM - for example) - the device reboots when navigating. I'm forced to use old maps with bad routing...

  • For example, the author of the topic complained that the route is not built as short as possible.

    OK. there's one other person. The OP didn't really provide enough information. It could be a issue with the basic map data.

    In one of your issues, you seem to be expecting the routing to work where there's no road or path.

    There's no way of eliminating map data being an issue in your case because we still don't know where these issues are occurring.

  • I expect a route where there is a path, because another device on the same route and the same map shows it (I have traveled to those places for many years). If you are a Garmin support employee, I am ready to provide all the data (coordinates of the start and end points of the route, map name *.img, coordinates of problem areas) that lead me to errors. Perhaps this will help solve the problem in which the route is not built for other users or gives an error.

  • None of these places appears to be your home or could be used to identify you. So, there shouldn't be any reluctance to providing the coordinates publicly. And a sufficiently-motivated person could figure it out from the screen shots (I don't want to work that hard).

    I've fixed numerous map problems around the world from the information people provided.

  • I've been having similar issues. Here is an example with concrete start / end positions (Guilford Town Green in Guilford,CT,USA to New Haven Union Station).
    I need to have the patience to remove ALL maps except one (disabling first, but actually removing next) and make sure edge 1000 and edge 1040 have the same 2023.10 US maps, to make sure there isn't an issue of too many maps, overlapping maps, etc.

    This time it is the routing that gives much longer than necessary routes, no matter what combination of settings I try.
    One concrete example - from near Guilford Town Green (say Old Whitfield St x Seaside Ave) to New Haven Union Station:

    RideWithGPS - 15.4mi 665ft
    Strava routing - 16.5mi 631ft

    Edge 1000 - 16.5mi (road bike / min distance / avoid all)
    Edge 1000 - 16.5mi (road bike / min distance / avoid nothing)
    Edge 1000 - 16.9mi (road bike / min ascent / avoid nothing)
    Edge 1000 - 16.9mi (road bike / min time / avoid nothing)

    Edge 1040 - 21.4mi 1426ft (road bike / min distance / avoid nothing / popularity off)
    Edge 1040 - 20.2mi 1423ft (road bike / min ascent / avoid nothing / popularity off)
    Edge 1040 - 20.7mi 1459ft (road bike / min time / avoid nothing / popularity off)

    Edge 1040 - 19.6mi 1397ft (road bike / min distance / avoid nothing / popularity on)
    Edge 1040 - 20.2mi 1422ft (road bike / min ascent / avoid nothing / popularity on)
    Edge 1040 - 19.5mi 1407ft (road bike / min time / avoid nothing / popularity on)

    Edge 1040 - 19.6mi 1402ft (road bike / min distance / avoid all / popularity on)
    Edge 1040 - 20.2mi 1375ft (road bike / min ascent / avoid all / popularity on)
    Edge 1040 - 39.6mi 2845ft (road bike / min time / avoid all / popularity on)

    No matter what setting I tried, no route got close to the obvious ones that any online routing app locked to. Even the 8yr old Edge 1000 had no problems.
    Each group of 3 above has minimize distance then ascent then time. Interesting to notice:
    1. Edge 1000 shortest was the minimize distance one, as expected.
    2. Edge 1040 pop off/no avoidance has the longest route given when set to 'minimize distance'???
    3. Edge 1040 pop on/avoid nothing has the shortest one when minimizing time (not distance)? By little, but it's the principle.
    4. Edge 1040 pop on/avoid all has the shortest when asked, the least ascent also correct, but impossible that the 39.6mi course with over 2x the climb it suggests is faster than any of the other two.

    What is going on?
    A. Some secret setting I am missing?
    B. Maps are like 2008 OSM, still full of no connects, unroutable roads, etc?
    C. Maps are perfect (same in Connect, I suppose?) but firmware is bad.
    D. I need to spend days trying different maps of different versions, enable, disable, download (it is so slooow)

    It seems the best solution for now is to bring along the Edge 1000 :-(
