    @Martin-Wilcke It looks like MRA is using the Garmin extensions to do their track and route calculations whereas Kurviger doesn't. The strange part is that for this exact same route if I use the OSM map in MRA the calculated time shows as 3:13, with the TomTom map it's 3:11 (both are close to the actual time that it took to ride the route and the time calculated by Google and Kurviger) and with the HERE map it is 4:17.

    Gpx 1.1 files exported by all three maps show that the tracks created used the Garmin extensions, however the actual route creation calculations must be a function of the underlying map itself.

    I pointed out in another post that the HERE map consistently does not follow an imported track as well as the other two, and the route's time calculations are definitely inferior as well.

    I definitely see the disadvantages of using the HERE map over using the OSM map in MRA. Can anyone tell me the actual advantages?

    Thanks!

    To avoid confusion: Using GPX extensions (like "Garmin extensions") is a way to store additional information in a gpx file that is not part of the core gpx data model. The most popular example is the differentiation between VIA and shaping route points using the garmin:trp extension.

    For time information, however, there is no need to use an extension as this is part of the core gpx data model.

    And it's about storing information and has nothing to do with time calculation.

      There is one I'm aware of: consideration of road closures.

        @Steve-Jarrell A small note on the side. I tried Kurviger a while ago and found the ETA's, while navigating, far too conservative (the rides were taking me less time). This was when driving a car on asfalt roads. They definitely don't include live traffic data and I think they have their own algorithm to calculate the ETA's. The ETA info to the next waypoint is a very important feature for my use cases and the conservative estimates in Kurviger were the main reason for me to switch to MRA (where I found the ETAs to be very accurate).

        @Herman-Veldhuizen Thanks for your respons Herman. With the TomTom and OSM maps I'm finding the calculated route times to be very accurate. With the HERE maps I find it to be inconsistent.

        The only thing that I can surmise is that the route calculations and the calculations that create a route from a track are built into the maps themselves and MRA has very little, if any, control over them otherwise the HERE map would not be inferior to the other two in this regard.

        I also switched from Kurviger as I find the user interface to be very, very unintuitive whereas I find MRA to be extremely easy to use. I also find MRA's tech support to be excellent, and the user forum is extremely helpful as well.

        Unless someone can show me why there are important advantages to using the HERE maps as the default I'm going to make the OSM maps my default, and hopefully the MRA developers will fix the bug that causes the following dialog to appear when I switch to the OSM map or import a track into it even though I have my driving mode set to "Driving" which, according to MRA, should avoid this message:

          @Steve-Jarrell I never really looked at the route times, only the ETAs while navigating.
          But now I did for one of my routes which goes mostly over a highway
          Route time for MRA-OSM is noticeably longer than MRA-Here! Kurviger is the slowest.
          220km, paths are very similar in all 3.

          MRA Here: 2h 52m
          MRA OSM: 3h 13m
          Kurviger: 4h 4m

            @Herman-Veldhuizen Thanks Herman.. That's weird..... there doesn't seem to be any consistency. My "gold standard" is normally Waze or Google maps as I find them to be extremely accurate, but since you can't upload a specific route into either they're of no help. Although you can import a track into Google MyMaps it really doesn't create a Google route from it, so it uses the tracks time information so that's no help.

            I could be wrong so if I am someone please let me know. I'm here to learn.... that's half the fun! 🙂

            If I have time I'll go back and compare 5 or 6 of our group's tracks/routes and compare them in MRA using the HERE, OSM and TomTom maps.

            Thanks for your input. I really appreciate it!

              The biggest advantage to use HERE maps for planning is the least chance for the planner map to be different than the navigation map. The advice is to plan your route on map that is ost equal to the one you navigate with. For MRA Navigation that is HERE, as is for Garmin devices. There are many differences in maps between OSM and HERE, especially in rural mountenesque areas.

              I am not aware of a driving mode called "driving". I only get this message when I switch from HERE or TomTom to OSM while I have "Motorbike" selected as driving mode.

              I am just an enthusiastic MRA user, and hope you will be one too!

                  @Martin-Wilcke Thank you.

                  That's one that I prefer not to use anyway as I've found (in our area at least) that often it's not accurate, or I'm creating a route that I'll be riding when they don't exist so I almost always disable it anyway.

                    @Con-Hennekens You are right. My mistake. It's called "Car" so I'm not set on Motorcycle, but I still get the message every time I switch to OSM. What driving mode are you using in your profile?

                    Thanks!

                            @BertM Yes, I've changed it back and forth several time experimenting trying to figure out what's going on.

                            If you look at my previous post you'll see where I took a screenshot of my profile setting set to "Car' at the exact same time that the error message is appearing.

                            I even thought that perhaps MRA considered the routing mode when the route was created from the track and then ignored it from then on, however I created the route from scratch by importing a .gpx file with the mode set to Car, and as soon as I did I got the error message.

                            Thanks for the response!

                              It's specifically the road after waypoint 26 that gives way longer estimates than other map sources. It's based on the realistic travel time HERE tracks for that section and my guess is that their data on that is wrong.

                              Either incorrect speed limit or some anomalies in their realistic travel time estimation

                              @Corjan-Meijerink After riding the route last Wednesday it is possible the HERE map is using information about the roads when they were really torn up after Hurricane Helene at the end of last year as some of them were still in pretty bad shape when we rode them and you could see where one lane the road had been washed completely out.

                              If the HERE map is using data from late last year it is likely that at that time their estimation of the time that it would take to ride this route would be accurate. Perhaps a future map update will resolve the issue. That's a very plausible explanation.

                              Thanks! I don't like mysteries, and I'll consider this one solved! 🙂
