GPX Versions 1.1 vs 1.2 for Garmin Visually Explained
-
Brilliant!
I have now created an out bound and inbound route.
Later on I will give it a try.
Thanks everyone for the patcience and time taken to answer my questions.
Pardon the pun but things are taking shape.@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.

@John-S-Parry I agree John.
If you don't include via points between your starting and ending via points and then skip them while navigating a route, it seems that you can rejoin your planned route manually if you have auto recalculation turned off with the 1.2 format. That's fine and easy to manage for me
That makes sense as basically (with my simplistic thought process) as a 1.2 route with only a beginning and ending via point is basically a track that's been converted to a route.
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!
For me personally if I just want a GPS to determine a route for me based on its on algorithms I'll just use Google Maps or Waze, but that's not why I use MRA! I want to determine exactly where I go when I'm riding!
Garmin, LEAVE MY ******** ROUTE ALONE!!! I don't need your help!!!

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......

@simon-james-hancock, also learned the hard way is if you start your route with 'CEP' (closest entry point) and either your end point or some other part of the route is closer to you than the start point, you can ride a very short route! In which case, choose the 'Start'.
If you wish to mark a petrol station or similar without creating a via point, create a POI of it in MRA. You can name it whatever you like and change the symbol. It will only show up as a flag and name on your Zumo though - these can be edited. There will be no distance or time shown to it but very handy nonetheless.
I'll reaffirm what I said earlier re 'auto-recalculate' with GPX1.2. It can be left on if you wish to be guided back to your route. It does not (in my tests) recalculate you to the next via point.
@Carl-Lee Very good to know. Thanks!!

@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.
