Projected elevation plot when navigating an auto-route. Is it correct on the F6? Looks like FINALLY FIXED.

Some of us using the Fenix 5 and 945 have noticed a problem with the predicted elevation plot/profile for an autorouted path, even just a straight-line path. It's discussed in https://forums.garmin.com/outdoor-recreation/outdoor-recreation/f/fenix-5-series/139809/projected-elevation-profile-still-wrong-since-v-7-10-when-navigating-a-route

Note that the problem DOESN'T appear for a saved activity or a downloaded course.
The problem shows up as a predicted elevation profile that is twice as 'bumpy' as it ought to be and apparently is for a 'there and back again' rather than a one-way route. It doesn't happen all the time though... if it did, it'd be better, but it's unpredictable.
I'd be fascinated to know it the Fenix 6 has the same problem.

Easy to test, you don't actually have to follow the path as this is about what the watch is predicting your elevation along the path will be, not the elevation that you actually do (that's another bug), just choose some point to navigate to, preferably something with a predictable elevation difference from where you are now. Saved locations are good if you have any but 'around me' features and 'points of interest' work too. You can have Activity set to Direct Routing in your "navigate settings->routing" settings if you want, that'll get you a straight line path but the elevation graph should still show you the ups and downs along that path. (You do need a map with elevation data but on my watch at least, the default maps have that)

Using the F5 menus, it's like: navigate->points of interest->cities->choose something->goTo->hit Start, wait for it to get gps fix and finish calculating and then scroll down until you see the elevation graph for your path. Is it suspiciously symmetrical? Does it show a ridge where you would expect only a slope? Or twice the expected number of ridges/mountain/bumps between you and your destination? Test it a number of times, say up to 10 times, to see if it is consistent. Using the same destination is OK.

Thanks in advance for any results! Here's a picture of a 'bad' result. Note how symmetrical it is about the centre. There should only have been one big ridge, not two. BTW, the distance shown is actually correct, just that the elevation graph is wrong.

I'd be interested too. For example, this is a video from my 945 : https://youtu.be/AeS0w_aS448 that exhibits this bug.

Nice demo of the problem. Well done.

No, same issue (Fenix 6x Pro Solar)

Reported that issue. But if I have read correctly, the issue is already present on the F5 series for about 2 years, so the issue should be known by Garmin...(?).

Damn! Thanks for confirming it and for reporting it. Perhaps that'll be some more ammunition to get it fixed on ALL of the Garmins that have it. Yes they know about it, but unbelievably haven't fixed it.

Also, it means I won't be forking out any $$$ on the F6 until this gets fixed. It's annoying enough having one watch with that bug.

I have seen it on my 5x plus, too. But I didn´t realize that it was a bug, thought I have done something wrong (user error) because it was gone with the next try. Because I normally work with added track/courses, I haven´t rarely seen it...

Unbelievable

Yes, it comes and goes, which is really aggravating. If it was consistent, we could work around it by ignoring the last half of the plot, which I kinda do anyway if it is really obviously symmetrical, but whaddya do when you don't know the terrain? Maybe there ARE two steep and nasty and strangely similar ridges between you and your destination...

I simply remove elevation plot data page and I use climb pro (isn't it the same thing?), but unfortunately, I think climb pro isn't available for 5X...

No not the same thing. ClimpPro may not show the whole elevation profil, it is made to show "single" climbs and the used algorithm may not show all climbs (because some climbs are no climbs for the algorithm, depands on the elevation and distance of the activity)...

Thank you! So with all Garmin devices (because this bug is still here for Fenix 5X, Fenix 5 Plus, 945, Fenix 6 and i suspect Marq) you can't know real elevation profile; i cannot trust in my watch if i previously don't know where is my destination, very disappointed! And it's unbelievable how Garmin doesn't care about such important bug that we are reporting since about 2 YEARS and affects practically ALL devices!
