Navigation Option Show "Original Route" Does Not Display Consistently

[Bouke Ent]

a track is not a orginal route. a track is a list off points in a sequeance. so track is not fixed with a map or road. with online calculation the server connects the points and looks if there is a road or path on the map and tries to follow that. offline is less able to do that and then you get straight lines between the points. because a track has many points it seem it is following the road. for old basecamp users it was the same. if calculation was not done or offroad you also got straight lines between points.

the white line can be 2 things. if you ride a route it can be the original route and it will show if you do recalculation and route takes a new way but it will follow the road. other option it is a route based on track information and then it depends on the calculation off the server or offline in app.

@Con-Hennekens just got back from an 8days tour in The Eifel. Since réception is por over there I user offline navigation all the t8me. I’ve noticed the the original route under my actual route was mostly bespied the route. Sometimes, mostly while driving hairpins it was way Off. Could using the offline mode be cousinage this

[Corjan Meijerink]

The calculated route is infinitely detailed
Routes stored by us have a certain resolution to not take up way too much space when syncing them. This results in the minor differences so to say.

The original route is a nice indicator of how you planned it so I personally would not be too bothered by it showing these minor divergences (in resolution due to missing coordinates, not actual route).

@Corjan-Meijerink sorry the divergences of the "original route" are sometimes not minor, they are major, hundreds of metres, plus the issue is the system is not consistent

if the original route can fit to the road correctly after the route is edited in the app route planner,
why does it not fit correctly when the last edit is done on the web planner?

[Con Hennekens]

@Brian-McG, are you saying that a web-planned route that shows these imperfections does NOT show those imperfections if it got last edited in the in-app planner? That would be interesting...

[Brian McG]

@Con-Hennekens yes that is what I am saying, it would be nice if someone could replicate
I am seeing the error in offline navigation
the route is edited in web planner - then synced to the device
the device is taken offline (airplane mode or wifi/network off)
the route is opened & navigation started with original route displayed

sometimes the web planned route appears ok with small errors as @Corjan-Meijerink expects
other times it can have larger errors & occasionally very huge errors
if I edit the web planned route in the app planner it seems to fit perfectly

I can understand the idea of trying to save storage, reduce data & speed up transfer
if the errors were always small then I would say - not a problem
when the error is large the original track line can obscure whole junctions & makes it difficult to read the map
for me the problem is the original route is not displayed consistently

I don't think a long term solution is to re-edit every route every time it is transferred/synced to the app

oh & don't forget the lack of contrast with a white original track
on the default garmin style map with this bug you can see nothing of the roads

[Con Hennekens]

@Brian-McG, This is a good find. Thanks for your elaborate explanation. I will try to replicate this behavior.

[Brian McG]

Sometimes the errors with the "original track" can be huge,
with the above route the "original route" is wrong by hundreds & hundreds of metres

what causes the wrong calculation of the "original route" in offline mode?

I have also noticed that with a route created in the web planner,
if the navigation is started with a network connection, the "original route" will fit perfectly to the road
the same as when the route is edited in the app planner, you get a perfect fit

I only seem to get the bad fit of the "original route" when I start the navigation in offline mode

[Con Hennekens]

@Brian-McG, Tried to replicate this some days ago, but did not succeed... Although I have seen these straight lines before too, I was not able to replicate it in any circumstance you described. I was surprised by that and don't understand why. Old routes, new routes, offline, online, changed in the webplanner, I could not get the straight lines to appear. I'll try again later, probably after the holiday season.

[Marinus van Deudekom]

I've seen the same behavior during my 8 days trip in the Eiffel 2 weeks ago. It was clear to see it when driving hair pins.
I was driving offline

[Nick Carthew]

I think the solution is to open the route when you have wi-fi, irrespective of whether you will navigate online or offline. I had this happen to me a few weeks back, so from that point I have always opened the route with wi-fi before navigating and I haven't had the problem since.

[Marinus van Deudekom]

@Nick-Carthew my problem was that the WiFi was Shi... To

[Brian McG]

@Nick-Carthew yes the problem only appears if you try to start to try navigating with the device offline i.e. with no internet, no wifi connection
the route must be last edited in the web planner

if you open/edit on the device with an internet/wifi/online connection, it will recalculate the "original route" & you won't see the problem

as far as I am concerned this is a definitive hard reproducible bug
I can replicate it on 3 different devices with 2 different accounts

now I know there are several work arounds, it is not so much of a big issue for me
just a pain having to go through extra steps to get things to work
but as this seems to be the norm for mra, things never quite work as expected ... hey ho

[Marinus van Deudekom]

@Brian-McG when the Devs find some time maybe they can fix it For me also low priority
