GPX Versions 1.1 vs 1.2 for Garmin Visually Explained
-
When you introduce an intermediate via point in the route and then skip it, you give the Garmin the permission to totally ignore your planned route and do whatever it wants to do and recalculate the route as it sees fit!
Via points have always been a nuisance if you don't visit them no matter what GPX format is used. I use them a lot on trek events where we have to visit multiple points but other than that use them very sparingly. Next time I get a chance, I'll build a 1.2 route with some extra via points and ride it. They'll be in places where the XT2 would find it a lot quicker to re-route in order to get to the next via point if skipped. I'm not sure when this will be but standby......
@Carl-Lee As long as you don't mind the Garmin rerouting you to get from via point to via point it's not an issue, but if you're expecting to follow the route that you planned you may or may not do so!

@Steve-Jarrell I am curious about one scenario under 1.2......
One of my favorite features in the Zumo is "Up Ahead". I've found it invaluable for locating gas stations and restaurants in areas I'm unfamiliar with. I was recently riding with a friend in the coastal Redwood forests along US-101 in far Northern California. Desolation doesn't describe how isolated that area is. We were heading south with no civilization is sight. And we were getting hungry.
On the Zumo, I selected "Up Ahead", then the Restaurant category, and saw a small town a few miles west of the route that had a highly rated burger place. I selected it, and the Zumo gave me the option of adding the diversion to my route. Again, I selected it and the off/on diversion worked perfectly. I'm wondering if under the covers that was a full route recalculate, and if my 1.2 route would have been altered up further ahead in an undesirable way?@John-S-Parry I'm not sure. That will be a good test. I will bet it does force a recalculate. However as has been pointed out here it very well may be device dependent (XT-XT2-XT3).
That's a beautiful part of the country. I flew into Seattle a few years ago and drove down the west coast mainly on the 101 to San Diego for a couple of weeks. The prettiest part of the drive was WA - OR - Northern CA by far.

@Steve-Jarrell Yes, the WA - OR - Northern CA sections of the west coast have incredible scenery. I always try to catch that area when there are known periods of good weather and clear skies. But from a pure riding perspective, Central California has some of the best backroad riding to be found anywhere. That's my backyard, and I try to take full advantage of it.
Back to the "Up Ahead" and what adding diversions does to a route -- I'll construct a test to see how much of the overall route is touched. Like you, I hate any recalculation because I never trust what might actually be altered. My routes have a given shape for a reason and changing them on the fly during execution goes against my intent. Using a feature like "Up Ahead" is a valid alteration (to me) given a specific circumstance, so I'll investigate that further.

So long as you have your track visible, none of this is a major problem. And in any case, it's always quite easy to get back to your intended route by stopping it then restarting with CEP.
I spend some time planning the specific roads I want us to go down so also hate it being messed up. I'm really pleased with how 1.2 handles a normal deviation so finding out about skipped via points and "Up Ahead" deviations will be interesting.

@John-S-Parry Yes, I have been rerouted onto some.... well let's say "interesting" roads that I didn't plan on being on in the past!

@Carl-Lee For some reason my XT3 is no longer showing my track with my route even though I've done it MANY times in the past. I'm still trying to figure out what's going on. You're right though... that's the very best way to know that you're being routed the way that you intended to be!

@steve-jarrell maybe as you are tied in to collections with Explore? This is how I am too and it’s a case of making the collection visible. A little more to it than that but I won’t blather on in case that’s not your issue.

@John-S-Parry Good deal. Let us know what you find.
The best test would be just a starting via point and an ending via point with a lot of shaping points in between that are neither the fastest or shortest paths to the ending via point. I'll try it if I get a chance. It's very likely that the older Garmin units will act differently than the new ons.

@Steve-Jarrell Good approach. I was thinking along the same lines. I'll mix up the roads enough to trigger a different re-calculated route path if that's what it wants to do.

@Carl-Lee No, I don't use Explore at all (I have another thread about the hoops that I had to go through to remove it when I did activate it) but I do use collections in the XT3.
You did put me on the right track though! Since I think this issue is unique to the XT3 I've created another thread to explain what's happening and a good work around as it's not documented at all in the user's manual.
Thanks!
p.s. When I said before that I've shown the track with the route many times I have..... but that's been with previous version of the Garmin units up to and including the XT.

@Simon-James-Hancock It appears from reading through all of this that your XT and XT2 will behave slightly differently with GPX 1.2 files. The XT and older Garmin devices will recalculate according to their own parameters if you use GPX 1.2 and accidently recalculate the route. This behaviour will not be fixed by Garmin as the units are now discontinued. I've tested this in simulation mode and riding the bike with a GPX 1.2 route on the Garmin Zumo XT you cannot let the unit recalculate. This is fine as all that happens is that the unit goes quiet until you re join the magenta line. For the XT2/3 it appears that recent software updates from Garmin mean that if you deviate from a GPX1.2 route you can leave automatic recalculation on and the device will navigate back to the route.
@Mzokk That is exactly what happened this afternoon in my test.
I purposly stopped along the route and turned both units off and then back on again.
The xt2 picked up the route again and the xt whent dorment untill much further down the route. -
Going off topic a bit.
If just using the MRA app on the phone, What is the best map to create the route and which format is the best to save the route for the MRA app?
How does the standalone MRA app deal with these situations?
I am asking this as my bike has carplay so therefore I also have the option of using the MRA app. -
The best map to use for route creation is the Here map as this matches the mapping on Garmin devices. If you have the navigation app you can create routes on it and they can be synchronised to your phone. If you are using the route planner on your phone (not the app) then you can download the routes if you have mobile phone signal or Wifi. They don't need to be saved in any format to the route planner only when you download a route to send to your device.
I use the app for navigation and have my phone synced with the site so if I have signal or wifi my route library is also on my phone (GPX files do not take up much space)

Do the routes perform in the same way as on the Garmin, ie when you go off route and recalculation?
