@Hans-Rutten the short answer is if you have an MRA Gold subscription to use the "Compare" tool [image: 1784883413629-9255862b-253c-4daa-960c-969d662d1a96-image.jpeg] In the above picture the algorithm being used to calculate the route is the Here algorithm & it can be "Compare" to the OpenStreetMap or TomTom route calculators the long answer .............. is that the routing algorithms that calculate the route for Here & TomTom are different, as is the underlying map data that the algorithms use to calculate the path of the route The larger the distance between any 2 points you place, the larger the number of possible different paths the algorithms can choose from & the greater the number of differences in the underlying maps (the average speeds on the roads) that the algorithms can also choose from In the picture below the route is a simple 2 points placed 66 miles apart & each of the different algorithms, Here (black line), OpenStreetMap (blue line) & TomTom (red line) calculate routes completely differently because of the difference in the algorithms & underlying data in their maps [image: 1784883595858-331a503d-393f-47ce-8de8-882a64982c22-image.jpeg] The same effect can happen when 2 points are placed closer together, 5 miles or even 1 mile apart IF there are different possible paths for the algorithms to choose from between 2 points it is possible for the paths to have different underlying data & the algorithms can calculate different routes The way to solve this is to "constrain" the route so that there are not 2 different paths for the algorithms to choose from This is done by adding extra points, normally shaping points, to force the route onto the preferred path of your choice. In the example I am using with 66 miles between points, adding an extra point constrains both OpenStreetMap & the TomTom algorithms to choosing a route via the west of London [image: 1784885466408-948a045f-3c04-4eb0-aca5-0936829f4017-image.jpeg] At the beginning & end of the route the OpenStreetMap route calculation is still different to that of the Here & TomTom routes because there are still multiple different optional paths for the algorithms to use even at this shorter distance Additional points would need to be added to more completely constrain the algorithms onto the same roads & make all 3 algorithms use the same route The above example with 66 miles between points, in an area like the south of the UK where there is a large network of roads, is extreme (or lazy) & is bound to cause problems with different routes being calculated, it is only an example to illustrate the issue. Normally you would place points a lot closer together depending on the density of the road network & the number of possible different path options between points If you are sharing your routes with friends that use navigation systems other than MRA, it is a good idea to make sure your routes are tightly constrained i.e. you add a lot of additional points to prevent the algorithms on the other navigation systems calculating a route via a different alternative path

@nomko without having a look at such a route its just guessing and I would like to give an answer given the facts

Yes, as a monopoly, you can get away with this! Just like you, every beta tester with an Android phone is now biting their nails, waiting for the long-awaited message!

@Brian-McG You are correct! I was able to force it to go straight thru by adding waypoints! But that brings in another interesting point. I know for sure that when HERE knows some road as "closed", there is no way you can force it to use it, no matter how many waypoints you try and add, unless you activate "disable seasonal closures". So, the fact that by adding more points I am able to force it to stay on tells me that these spots are NOT designated as "closed" on HERE maps. Then, in this example Bear Tooth is the main road and with no avoidances selected why in the world would the HERE algorythm start taking you off the main road? What am I missing here?

@steve-jarrell, I agree with all that you wrote and that is what I have previously found to be correct. I either exported a 1.2 file via USB to my SD card or used 1.1 via Tread. Both worked although if you stopped the 1.2 route and re-started it, Tread would probably corrupt it. I'm aware of how to remove Tread from the mix but I obviously seem to like a problem to solve. As of recently, 1.2 is now playing nicely with Tread so getting a route into my XT2 is a doddle. I know the route is correct because I run the track in red underneath it. The two do not separate and re-routing back is catered for (if you should so wish). All I'm trying to say is that for those who are either having trouble with Tread or who have binned it but would like to use it, try it again with 1.2. I like the ability to plan with MRA and loading this route when away from home. The SD card option is too fiddly - I don't much fancy dropping it as it has lots of music on it too.

enjoy the country side. hope it isn't raining cats and dogs

Dit is SUPER!, ongelooflijk hoe jullie met zo'n kleine groep mensen dat voor elkaar krijgen. Voor allemaal super bedankt en in dit geval Cor-Jan

Ik ben niet meer te helpen, ik ben reddeloos verloren

@Apatrida-2-0 Cuando lo uses, no querrás cambiar. Es el mejor planificador y conjuntamente con su navegador, no tiene rival. Ya hace tiempo que lo uso y ni siquiera exporto los GPX para tenerlos por si he de usar otro navegador... porque no lo he necesitado (por ahora). Saludos, y nos vemos en la carretera (perdon @b0hd1 por el plagio )

@Edwin_M Thank you for sharing our Tool Edwin! Good to hear you like it.

@Lynchy67 It is on the list for major maintenance of the website, just like being able to export multiple routes in one go. Please be patient.

@Garry-Davis exactly, that would have been my second advice, but you are one step ahead. You can choose your beloved app, to count a route to the petrolstation

Hi ! So, the bad news is that Transfagarasan is still closed for now, but it should be opened in the next two weeks. You can check the live cam from time to time: https://www.roxy-world.ro/webcam-transfagarasan Good news is that Transalpina was opened about 5 days ago, some of my friends went there already and confirmed this. Enjoy Romania !
